From conventional inorganic semiconductors to covalent organic frameworks: advances and opportunities in heterogeneous photocatalytic CO₂ reduction

Abstract

Solar-driven photochemical CO2 reduction over semiconducting materials is a strategic technology towards sustainable development as it represents a source of renewable liquid and gaseous fuels, and simultaneously provides a solution...

Harnessing the power of MXenes: a comprehensive exploration of their photocatalytic potential in mitigating hazardous dyes and CO2 reduction

“…Consequently, in recent decades, researchers have preferred MXenes photocatalysts to degrade various pollutants. MXenes exhibit favourable properties and enhanced efficiency as photocatalytic materials [93][94][95]. MXenes, characterized by outstanding conductivity ranging from 6000 to 8000 S/cm, are notable for a range of commendable properties that extend beyond their conductivity.…”

Novel benzimidazole-linked microporous conjugated polymers for highly selective adsorption and photocatalytic reduction of diluted CO2

“…, CO, CH 4 and CH 3 OH) in a sustainable way, while also alleviating the environmental crisis caused by excessive CO 2 emissions. 1,2 In the past few decades, a large number of photocatalysts with high efficiency have been investigated for CO 2 reduction, but these photocatalytic systems usually use a pure CO 2 atmosphere, which needs to be extracted and purified from air first. 3–6 As is known, the actual CO 2 concentration in the industrial exhaust gas, such as the flue gas emitted from coal-fired power plants, is generally below 15%.…”
