Dec 01, 2014· Sol-gel Processing The sol-gel process is a wet-chemical technique that uses either a chemical solution (sol short for solution) or colloidal particles (sol for nanoscale particle) to produce an integrated network (gel). Metal alkoxides and metal chlorides are typical precursors.
The defective sites act as electron traps, which depress the photocatalytic hydrogen evolution activity. However, by combining ball milling and photodeposition of Rh, highly improved hydrogen generation rates for CsTaWO 6 are achieved. The sol–gel citrate route finally leads to more active materials than the solid state reaction.
