Nitrogen vacancies and metal-free group intercalation on carbon nitride for super photocatalytic performance

Insight into the rapid degradation of antibiotic rifampicin by W-doped O-bridged g-C3N4via the coupling effect of electron replenishment in the dark degradation stage and electrophilic attack in the photocatalytic stage: experiments and DFT simulation calculations

“…32 Numerous studies have reported that functional group doping has a more signicant impact on the charge transport of catalysts compared to single element doping, thereby greatly improving photocatalytic activity. [33][34][35] For example, Zhang et al successfully prepared g-C 3 N 4 containing cyanide and hydroxyl groups via the water-bath age-hard template method and completely degraded bisphenol A within 15 min, with a reaction rate 39.6 times that of pure g-C 3 N 4 . 35 Recently, most of the related studies on g-C 3 N 4 have focused on non-metallic groups, but few studies have been conducted on the role of metallic groups.…”

“…35 Recently, most of the related studies on g-C 3 N 4 have focused on non-metallic groups, but few studies have been conducted on the role of metallic groups. 34,[36][37][38] This work is of great signicance for exploring the effect of metallic group doping on the structure and properties of photocatalysts.…”

NiS2-Coated Carbon Fiber Paper Decorated with MoS2 Nanosheets for Hydrogen Evolution

“…Recently, the over consumption of fossil fuels has resulted in global energy crisis and serious environmental pollution. − In order to solve the problems, it is necessary to develop clean and renewable energy. At present, the existing clean energy such as hydrogen and solar energy and so on has been widely concerned. , Hydrogen, as a kind of sustainable and clean energy, has been regarded as an alternative to fossil fuels. , There are many ways to produce hydrogen. Electrocatalytic overall water splitting driven by renewable energy (wind energy or solar energy) is one of the most effective and attractive methods. − The water electrolysis process has two half reactions: one is the hydrogen evolution reaction (HER) and the other one is the oxygen evolution reaction (OER). − However, the efficiency of electrocatalytic overall water splitting is greatly limited by the inherently sluggish kinetics of the HER.…”

Pt-Doped Biomass Carbon Decorated with MoS2 Nanosheets as an Electrocatalyst for Hydrogen Evolution

“…The overconsumption of non-renewable fossil energy such as coal and oil has resulted in serious environmental problems. − Against the backdrop of goal of carbon peaking and carbon neutrality, the renewable and clean energy such as solar energy, hydrogen, wind energy, and so on has developed rapidly. − Hydrogen, as a kind of low-carbon, clean, and sustainable energy, has been regarded as an alternative to fossil fuels. − Electrocatalytic overall water splitting is considered an efficient technology to produce hydrogen owing to its clean and sustainability. − Water electrolysis process has two half reactions: hydrogen evolution reaction (HER) and oxygen evolution reaction. , However, the high overpotential and sluggish kinetics limit the development of HER, which influences the efficiency of electrocatalytic overall water splitting. It is necessary to develop an efficient hydrogen evolution catalyst to improve the efficiency of HER. − …”
