Carbon quantum dots (CQDs) are discrete, quasi-spherical carbon nanoparticles with sizes below 10 nm. The properties of CQDs can be further enhanced by doping elements such as nitrogen, phosphorous, sulphur, and boron or co-doping heteroatoms nitrogen-phosphorous, nitrogen-sulphur, nitrogen-boron. These excellent utilized to enhance the photocatalytic performance semiconductors. Therefore, in this review, we summarize different types bare CQD-scaffolded semiconductors, both doped co-doped, used for hydrogen production. Moreover, detailed mechanism CQD/semiconductor-based production is reviewed. Recent progress design development CQD-based photocatalysts, along challenges involved, comprehensively

Water splitting for hydrogen generation under exposure to sunlight is an excellent technique generating sustainable power and mitigating the consequences of climate change. Numerous attempts have been made synthesize superior nano-composite elements. Several constraints still prevail at every stage development a photoreactor system, from scalable production photocatalyst (PC) material fabrication ideal structure having high transfer mass, effective charge carrier separation, mobility, required bandgap band edge positions, photon absorption, stability. In this chapter, recent developments in photocatalysts, including metal doping, surface photosensitization, defect engineering, copolymerization, novel architectures, are discussed. The design system also major concern, as it plays significant role achieving desired output. This chapter aims give thorough explanation main obstacles encountered while scaling up PC devices suggest some possible remedies its use commercially viable solar hydrogen. conclusion, important aspects influencing performance highlighted, recommendations future research based on assessment most experimental proposed.

Photo-electrochemical and photocatalytic technologies are promising solutions for solar fuel production involve a number of physical chemical phenomena. We provide an overview numerical analytical tools to describe such phenomena occurring at disparate time space scales within devices as photo-electrochemical cells photo-chemical reactors. On one hand, include photo-induced electron transfer, charge separation, recombination, equilibrium reactions between species in adsorption reactions. the other examples transport or self-assembling molecular structures. In this respect, we critically review macroscale continuum models combined with kinetic descriptions including their possible coupling even lower scales. specifically focus on atomistic coarse-grained able represent local environment reactive interfaces photoelectrodes supra-molecular assemblies. The critical role latter structures photochemical conversion is highlighted: Therefore, morphological structure self-assemblies, micelles monolayers, solution solid–liquid gas–liquid also discussed. Finally, important scientific gaps identified perspectives future research outlooked.
