Photoreforming (PR) is a process that splits water into hydrogen coupled with oxidation of solid waste into value-added products, which provides a way to mitigate resource depletion of solid waste and accumulation of CO 2 in the atmosphere. The realization of solid waste PR by harnessing the redox capabilities of photocatalyst is crucial to address the environmental pollution issue and reduce our reliance on fossil fuels. In this review, we overview the continuous progress from the latest studies in constructing the PR system for upgrading of solid waste. We classify the different kinds of solid wastes and illustrate the PR mechanism. Furthermore, we discuss the advantages for cooperatively coupling of hydrogen production with solid waste valorization. We also highlight some state-of-the-art photocatalysts for valorization of biomass, plastics, and food wastes. Finally, we focus on the development of high-performance catalysts needed in the PR domain to tackle the future challenges.

“…Approximately million pounds of trash from businesses and agricultural farms enters natural resources, according to a United Nations assessment from 2013. To remove contaminants from water, numerous traditional procedures such as reverse osmosis, filtration, adsorption, sedimentation, chemical and biological treatments, and membrane filtering have been widely employed [9]. The most common wastewater mitigation methods available today, such as adsorption and coagulation, simply move the effluent into a different phase [10].…”

Pollution by textile dyes on waterbodies is an issue for both human health and the environment. To remove/degrade dyes, many approaches (coagulation, membrane separation, and adsorption) have been investigated. However, the use of semiconductor-assisted materials in conjunction with sustainable solar energy has emerged as a possible solution to the problem. Although single component photocatalysts have been tested, composites of semiconductor materials are being employed owing to their low efficiency and stability due to the high recombination rate electron-hole pair and inefficient visible light absorption. By combining two or more semiconductor components, semiconductor heterojunction systems are created. Overall stability is increased by the synergistic impact of their features, such as adsorption and better charge carrier movement. This paper discusses current advances in advanced nanocomposite materials utilized as photocatalysts, as well as the utilization of heterojunctions, crystallinity, and doping to improve photocatalytic characteristics. The conclusion includes a summary, research gaps, and a forecast for the future. This study will aid in the development of efficient heterostructure photodegradation systems by providing a comprehensive appraisal of recent advances in demonstrating effective nanocomposites for photodegradation of Rhodamine B dye under ideal circumstances.

“…It can be used not only as a fuel, but also as a raw material for the production of hydrocarbon, ammonia, and other chemicals . Currently, more than 95% of industrial H 2 comes from steam reforming of coal and natural gas, which consumes huge energy and emits CO 2 . The utilization of renewable solar energy to obtain “green H 2 ” from water decomposition is a promising strategy in the face of an increasingly severe energy crisis and environmental contamination.…”

Semiconductor photocatalysis has demonstrated a promising potential in solving the energy crisis and environmental pollution. In the past few years, hexagonal ZnIn 2 S 4 has received increasing attention in photocatalysis due to its relatively narrow band gap, strong reducing power for hydrogen evolution reaction (HER), excellent chemical stability, nontoxicity, as well as low cost. This Review summarizes the latest advances of ZnIn 2 S 4 -based photocatalysts for the conversion of solar energy to hydrogen production, accompanied by selective organic oxidation to obtain value-added chemicals and organic pollute degradation. First, the basic crystal structure, photoelectric properties, and preparation methods of ZnIn 2 S 4 are briefly introduced. Three typical kinds of modification strategies including defect engineering, cocatalyst loading, and heterojunction fabrication then are summarized. As for the photocatalytic activity, besides the conventional HER in the presence of hole capturers, we have highlighted the developments of ZnIn 2 S 4 -based photocatalysts for H 2 production via overall water splitting, and H 2 production coupled with selective oxidization of organics and with degradation of organic pollutes. Last, some challenges that ZnIn 2 S 4 would face to realize application in solar energy conversion and environmental protection are presented.
