After Industrial Revolution, energy has been recognized as an important factor which enhances the motive power for industry in the industrial society. However, recently the excessive consumption of energy pursuant to the rapid expansion of industry created serious problems of the exhaustion of fossil fuels as well as unusual change in the weather due to the mass discharge of carbon dioxide. We can say that after all proposals will boil down to the development of New & Renewable energy. The most suitable source of energy for this required change is solar energy. The advantages of solar energy are that it is renewable, infinite supplied and environmentally safe energy source, and the method of energy supply is in small scale and is decentralized. However, solar energy related products have the problems such as the limitation for installation, problems in maintenance and insufficient reliability, which have been the barrier to consumers to satisfy the purchase need for solar heat related products. In this research will perform thermodynamic analysis through the application of infrared ray thermal imaging camera and will discuss about the applicability of solar energy system and other fields as well.

Energy Independence

This article explores uses of solar energy as a substitute to fossil fuels. Solar energy is usually considered in terms of making electricity; however, it also has the potential to supplant fossil fuels in the production of liquid fuels, and in driving endothermic industrial processes. Solar thermochemical processes are feasible, and a solar power concentration process that harnesses sunlight’s infrared energy is the best suited technology for making solar fuels a reality. Another area in which solar commodity production may have advantages over traditional industrial practice is in the separation of pure metal and oxygen from metal oxides found naturally in many ore deposits. Solar fuels can provide a stable and strategically important energy resource; some may consider them to be the ideal solution for sustainable energy independence. Solar thermochemistry could potentially have the biggest impact in the production of hydrogen-derived fuels which would be capable of replacing those derived from fossil fuels.

Energy Sources

Energy is the most important issue of the 21st century. Due to severe environmental problems, mainly related to air pollution of urban areas and green house effects leading to global warming, fossil fuels need to be replaced by renewable energy sources. Beside the wind energy, which is progressively more and more exploited, solar energy represents a clean, abundant, diffuse and economical energy which can be converted into heat, electricity or in the form of so called solar fuels, provided special materials are developed able to efficiently absorb solar light and produce charge separation. This is the prerequisite for obtaining electricity from sunlight and solar fuels, e.g. hydrogen from water photosplitting or carbon containing species from carbon dioxide photoinduced reduction, which can be stored and used on need. Converting solar energy into chemical energy is thus a big challenge for chemistry.

Biodiesel is a promising alternative to fossil fuels and mainly produced from oils/fat through the (trans)esterification process. To enhance the reaction efficiency and simplify the production process, various catalysts have been introduced for biodiesel synthesis. Recently, the use of bio-derived catalysts has attracted more interest due to their high catalytic activity and ecofriendly properties. These catalysts include alkali catalysts, acid catalysts, and enzymes (biocatalysts), which are (bio)synthesized from various natural sources. This review summarizes the latest findings on these bio-derived catalysts, as well as their source and catalytic activity. The advantages and disadvantages of these catalysts are also discussed. These bio-based catalysts show a promising future and can be further used as a renewable catalyst for sustainable biodiesel production.

Electromagnetic light from the Sun is the largest source, and the cleanest energy available to us; extensive efforts have been dedicated to developing science and engineering solutions in order to avoid the use of fossil fuels. Solar energy transforms photons into electricity via the photovoltaic effect, generating about 20 GW of energy in the USA in 2020, sufficient to power about 17 million households. However, sunlight is erratic, and technologies to store electric energy storage are unwieldy and relatively expensive. A better solution to store energy and to deliver this energy on demand is storage in chemical bonds: synthesizing fuels such as H2, methane, ethanol, and other chemical species. In this review paper we focus on titania (TiO2) nanotubes grown through electrochemical anodization and various modifications made to them to enhance conversion efficiency; these semiconductors will be used to implement the synthesis of H2 through water splitting. This document reviews selected research efforts on TiO2 that are ongoing in our group in the context of the current efforts worldwide. In addition, this manuscript is enriched by discussing the latest novelties in this field.

Since the second industrial revolution, the use of fossil fuels has been powering the advance of human society. However, the surge in carbon dioxide (CO2) emissions has raised unsettling concerns about global warming and its consequences. Membrane separation technologies have emerged as one of the major carbon reduction approaches because they are less energy-intensive and more environmentally friendly compared to other separation techniques. Compared to pure polymeric membranes, mixed matrix membranes (MMMs) that encompass both a polymeric matrix and molecular sieving fillers have received tremendous attention, as they have the potential to combine the advantages of both polymers and molecular sieves, while cancelling out each other’s drawbacks. In this review, we will discuss recent advances in the development of MMMs for CO2 separation. We will discuss general mechanisms of CO2 separation in an MMM, and then compare the performances of MMMs that are based on zeolite, MOF, metal oxide nanoparticles and nanocarbons, with an emphasis on the materials’ preparation methods and their chemistries. As the field is advancing fast, we will particularly focus on examples from the last 5 years, in order to provide the most up-to-date overview in this area.
