As a great threat to all livings on earth, waste artificial plastics now are everywhere, from oceans our cells [1]. The world cannot withstand the growing plastic in million tonnes every year, which has already caused environmental pollution and economic losses [2]. Besides efforts for preparing novel with self-decomposition ability, methods needed clear away these leftover history or recycle w...

Since the 1970s, splitting water using solar energy has been a focus of great attention as a possible means for converting solar energy to chemical energy in the form of clean and renewable hydrogen fuel. Approaches to solar water splitting include photocatalytic water splitting with homogeneous or heterogeneous photocatalysts, photoelectrochemical or photoelectrocatalytic (PEC) water splitting...

The problem of textile dye pollution has been addressed by various methods, mainly physical, chemical, biological, and acoustical. These methods mainly separate and/or remove the dye present in water. Recently, advanced oxidation processes (AOP) have been focused for removal of dye from waste water due to their advantages such as ecofriendly, economic and capable to degrade many dyes or organic...

Photocatalytic hydrogen peroxide (H2O2) production from O2 and H2O is an ideal process for so-la-to-chemical energy conversion. Herein, ZnO nanorods are prepared via a simple hydrothermal method photocatalytic H2O2 production. The exhibit varied performance with different calcination temperatures. Benefiting calcination, the separation efficiency of photo-induced carriers significantly improved...

The present study examined the gas-phase photocatalytic degradation of toluene using ZnO-SnO2 nanocomposite supported on activated carbon in a photocatalytic reactor. Toluene was selected as a model pollutant from volatile organic compounds to determine the pathway of photocatalytic degradation and the factors influencing this degradation. The ZnO-SnO2 nanocomposite was synthesized through co-p...

Semiconductor photocatalysts have attracted increased attention due to their great potential for solving energy and environmental problems. The formation of Z-scheme photocatalytic systems that mimic natural photosynthesis is a promising strategy to improve photocatalytic activity that is superior to single component photocatalysts. The connection between photosystem I (PS I) and photosystem II...

Photocatalysis provides a prospective approach for achieving high-value products under mild conditions. To realize this, constructing selective, low-cost and environmentally friendly photocatalyst is the most critical factor. In this study, BiOBr/Zn@SnO2 fabricated by one-pot hydrothermal synthesis method BiOBr: SnO2 ratio 3:1; material applied as in fructose selective conversion to lactic acid...
