Polymer Templates

In this work, novel monolithic carbon aerogels obtained by using a polymer template method were characterized and evaluated for their applications in the hydrogen and deuterium adsorption capacity. The properties (i.e., surface area, pore size distribution, hydrogen and deuterium adsorption capacities, etc.) of the carbon aerogels were affected by the polymer templates. The results showed that the carbon aerogel with the molar ratio of polyacrylic acid (PAA) to zinc chloride (ZnCl2) being 0.75:40 was featured the highest surface area (1806 m2/g) and had the highest hydrogen adsorption capacity. Moreover, the deuterium adsorption capacity of the carbon aerogel was to be further elucidated.

Cyclic Voltammetry Test

The ultra-low density carbon aerogel, as low as 20 mg/cm3, was fabricated by pyrolysis of the organic aerogel formed by aqueous condensation of resorcinol and formaldehyde. Its surface area was as high as 1783 m2/g and it was used for investigation of electrochemical capacitive behaviours. The ultra-low density carbon aerogel displayed capacitive performance (110 F/g at 0.2 A/g) in 6 M KOH aqueous solution. Additionally, over 98% of the initial capacitance was retained after repeating the cyclic voltammetry test for 1000 cycles. The electrochemical performance might be attributed to the combination of three dimensional “opened” structure and high surface area of the carbon aerogel.

Spinel Oxides

The binary mesoporous spinel oxides with high surface area have been synthesized by using KIT-6 and SBA-15 as hard templates and hydrated nitrated salts as precursors. Low temperature such as 500 °C is suitable for preparation of NiCo2O4with spinel phase. High temperature such as 800 °C is necessary for preparation of NiMn2O4, MnCo2O4, and (Co0.5Mn0.5)3O4with pure spinel phase. The prepared mesoporous spinel shows high surface area as 43-105 m2/g with pore volume as0.095-0.233 cm3/g. It is preferred to form mesoporous NiCo2O4with spherical particles.
