Increasing CO2 concentration in the atmosphere is believed to have a profound impact on the global climate. To reverse the impact would necessitate not only curbing the reliance on fossil fuels but also developing effective strategies capture and utilize CO2 from the atmosphere. Among several available strategies, CO2 reduction via the electrochemical or photochemical approach is particularly attractive since the required energy input can be potentially supplied from renewable sources such as solar energy. In this Review, an overview on these two different but inherently connected approaches is provided and recent progress on the development, engineering, and understanding of CO2 reduction electrocatalysts and photocatalysts is summarized. First, the basic principles that govern electrocatalytic or photocatalytic CO2 reduction and their important performance metrics are discussed. Then, a detailed discussion on different CO2 reduction electrocatalysts and photocatalysts as well as their generally designing strategies is provided. At the end of this Review, perspectives on the opportunities and possible directions for future development of this field are presented.

The silver halides and their corresponding composites would constitute remarkable photocatalytic systems not only in energy production but also in environmental remediation. The major advantage in these silver halides system is that plasma metal Ag 0 species would be spontaneously generated by silver halides under light irradiation, which play dual roles of expanding light absorption range and charge carriers separation. In this tutorial review, the origin and development of silver halides, synthesis methods, construction of composite structures with other materials, photocatalytic applications, and various and controversial mechanisms are all exhaustively described.

“…In recent years, the g-C 3 N 4 nanostructured materials have been studied for CO 2 photoreduction [92,165], due to their excellent stability, sufficiently negative CB energy and narrow band gap. Many strategies are reported to promote g-C 3 N 4 with condensed matter and molecular sensitizers [166,167], such as doping with metals [168,169] and non-metal [170][171][172], heterojunction construction [173][174][175][176] and Z-scheme composites employing co-catalysts [165][166][167]173,175]. Pengfei et al reported ultrathin C 3 N 4 nanosheets for enhanced photocatalytic CO 2 reduction [177] in which surface functionalization and textural modification by NH 3 -mediated thermal exfoliation enhanced light harvesting, charge-carrier redox potentials, and the surface area for CO 2 adsorption (to 0.2 mmol·g −1 ), resulting in CH 4 and CH 3 OH productivities of 1.39 and 1.87 µmol·h −1 ·g −1 respectively, a five-fold increase over bulk g-C 3 N 4 .…”

Graphitic carbon nitride (g-C 3 N 4 ) is a promising material for photocatalytic applications such as solar fuels production through CO 2 reduction and water splitting, and environmental remediation through the degradation of organic pollutants. This promise reflects the advantageous photophysical properties of g-C 3 N 4 nanostructures, notably high surface area, quantum efficiency, interfacial charge separation and transport, and ease of modification through either composite formation or the incorporation of desirable surface functionalities. Here, we review recent progress in the synthesis and photocatalytic applications of diverse g-C 3 N 4 nanostructured materials, and highlight the physical basis underpinning their performance for each application. Potential new architectures, such as hierarchical or composite g-C 3 N 4 nanostructures, that may offer further performance enhancements in solar energy harvesting and conversion are also outlined.
