Synthesis of layered compound from walnut shell by template method TiO2/CdS/CoP application of photocatalyst in efficient hydrogen productions

The photocatalytic H2 production requires catalysts with specific and optimized crystal morphology, surface area and interfacial bonding. In this work, we used a template based on walnut shell biomass to prevent particle aggregation. Using this approach, we obtained nano-TiO2 with a brookite structure. CdS nanoparticles were then grown in situ on the TiO2 surface. This material was then combined with the inexpensive non-noble-metal cocatalyst...
