Cornstalk biochar-TiO2 composites as alternative …
WebJun 5, 2024 · When biochar is added to form a composite, it can promote light absorption . However, there is an ideal biochar/photocatalyst ratio, and this varies according to the source of the biochar. An excess of biochar leads to a reduction in photocatalytic efficiency because it blocks the light that reaches the surface of the catalyst [113, 133]. WebApr 20, 2024 · There are numerous reports on the narrowing of the bandgap of photocatalytic nanomaterials with biochar due to (1) formation of a localised electron trapping site below the CB of photocatalyst that prevents recombination and (2) effective charge transport by the metal-oxygen-carbon linkage between biochar and … howe city council
