Supported particles are easily accessible as standard materials used in heterogeneous catalysis and photocatalysis. This article addresses our exemplary studies on the integration of supported nanoparticles into their solid support, namely gold nanoparticles into zinc oxide sub-micrometer spheres, by energy controlled pulsed laser melting in a free liquid jet. This one-step, continuous flow-thr...

Semiconductor photocatalysts, especially semiconductor heterojunctions, have great development potential in the field of photocatalysis. SnO 2 /g-C 3 N 4 heterojunction has shown excellent photocatalytic performance rather than single or g-C , particularly for visible-light-driven In this review, synthesis methods are summarized. Then, modification strategies morphology control, defect introduc...

Light-driven semiconductor-catalyzed oxidation reactions are of fundamental importance in photocatalysis and photoelectrocatalysis for removing organic contaminants in wastewater, solar energy conversion, and fine chemical synthesis. The underlying reaction mechanism is often unclear because it is difficult to measure directly and specifically the semiconductorcatalyzed reaction rates. For exam...

With a distinct electronic structure and unsaturated coordination centers, supported single-atoms (SAs) have shown great potential in heterogeneous catalysis due to their superior activity, stability, selectivity. Over the last few years, fascination of SA-use spread also over photocatalysis, i.e., particular case which chemical reactions are activated by charge transfer from an illuminated sem...

Although the history of photocatalysis research is not so long, many researchers have studied photocatalysis and a large number of papers on photocatalysis have been published. The objectives of this review paper are to revisit the fundamentals of photocatalysis, especially its thermodynamics and kinetics, which have not been reexamined in recent studies, to clarify the problems, if any, that p...
