Fundamental Requirement

Energy is the fundamental requirement of all physical, chemical, and biological processes which are utilized for better living standards. The toll that the process of development takes on the environment and economic activity is evident from the arising concerns about sustaining the industrialization that has happened in the last centuries. The increase in carbon footprint and the large-scale pollution caused by industrialization has led researchers to think of new ways to sustain the developmental activities, whilst simultaneously minimizing the harming effects on the enviroment. Therefore, decarbonization strategies have become an important factor in industrial expansion, along with the invention of new catalytic methods for carrying out non-thermal reactions, energy storage methods and environmental remediation through the removal or breakdown of harmful chemicals released during manufacturing processes. The present article discusses the structural features and photocatalytic applications of a variety of metal oxide-based materials. Moreover, the practical applicability of these materials is also discussed, as well as the transition of production to an industrial scale. Consequently, this study deals with a concise framework to link metal oxide application options within energy, environmental and economic sustainability, exploring the footprint analysis as well.

Nanostructured TiO2-based Z-scheme heterojunctions have been widely accepted to be among the most effective photocatalysts for environmental remediation owing to their broadened light absorbance, high efficiency of photogenerated charge carrier separation, and well-preserved strong oxidation and reduction capability. In this review, we will first introduce the photogenerated charge carrier transportation mechanism of three different types of Z-scheme heterojunction systems, namely, liquid-phase Z-scheme photocatalytic system, all-solid-state indirect Z-scheme photocatalytic system, and all-solid-state direct Z-scheme photocatalytic system. Subsequently, we will describe the recent advances toward the rational design and fabrication of all-solid-state nanostructured TiO2-based Z-scheme heterojunctions. The applications of the thus-constructed all-solid-state nanostructured TiO2-based Z-scheme heterojunctions in the degradation of volatile organic compounds, removal of waste water organic pollutants, and upgradation of greenhouse gas CO2 will then be presented one by one. Finally, the advantages and disadvantages of all-solid-state nanostructured TiO2-based Z-scheme heterojunction for photocatalytic environmental remediation will be briefly discussed, and the direction of future development will be prospected as well.
