A Comprehensive Review on the Boosted Effects of Anion Vacancy in the Photocatalytic Solar Water Splitting: Focus on Sulfur Vacancy

“…In general, semiconducting-based photocatalytic PC and PEC water splitting have been broadly studied to address environmental and energy issues by converting solar light to H 2 and O 2 . The carbon-free and renewable fuel is hydrogen.…”

“…In general, semiconducting-based photocatalytic PC and PEC water splitting have been broadly studied to address environmental and energy issues by converting solar light to H 2 and O 2 . 56 The carbon-free and renewable fuel is hydrogen. Due to other advantages of easy storing and transportation, high energyper-mass content has gotten a promising interest to be produced photocatalytically via water-splitting solar energy conversion.…”

A Comprehensive Review on the Boosted Effects of Anion Vacancies in Photocatalytic Solar Water Splitting: Focus on g-C3N4 with Carbon and Nitrogen Vacancies

“…Over the decades, a promising renewable resource, solar energy, has received extensive attention to meet sustainable energy development needs. , Thus, some efforts have been made to use it in various clean energy sources, such as fuel cells. − Accordingly, solar-light water splitting is an efficient strategy for H 2 evolution, the ideal energy because of its combustion product, H 2 O, and high energy density. , Since the first H 2 production via photoelectrochemical (PEC) water splitting on an n-type TiO 2 electrode in 1972, critical attention has been paid to green, environmentally friendly, and carbon-free fuel production via photocatalytic (PC) water splitting . In this regard, PC conversion of direct solar energy into chemical energy is considered a critical solution to reaching a sustainable energy supply and environmental remediation because only 5% of solar light is UV light, which can only be utilized by broad-band-gap semiconductor catalysts. , In addition, due to their application as semiconductors via the fast recombination of photogenerated charges (electron–hole (e/h) pairs) induced upon light absorption, the development of broad solar absorption photocatalysts with suppressed e/h recombination is of great interest to yield high PC efficiency. − Thus, visible-light-active semiconductors have attracted critical attention for PC H 2 production. − …”
