“…Other harmful gases in the exhaust gas may also lead to poisoning of the metal catalyst and reduce the service life of the stimulus. [132][133] However, the energy consumption to purify and clean industrial waste gas to obtain high purity CO 2 is significantly elevated, which contradicts the reduction of CO 2 emissions. [134] Secondly, the current use of metal aerogels for electrocatalytic CO 2 RR requires enormous power consumption, which is also against the energy saving and emission reduction rule.…”

General strategies for metal aerogel synthesis, including single-metal, transition-metal doped, multi-metaldoped, and nano-metal-doped carbon aerogel are described. In addition, the latest applications of several of the abovementioned metal aerogels in electrocatalytic CO 2 reduction are discussed. Finally, considering the possibility of future applications of electrocatalytic CO 2 reduction technology, a vision for industrialization and directions that can be optimized are proposed.According to the available studies, copper is the only recognized multiphase catalyst for electrocatalytic CO 2 reduction to generate various hydrocarbons and their oxides, such as ethanol and ethylene. [61] Therefore, this review explores the mechanism of CO 2 reduction by electrocatalytic reduction of CO 2 on the surface of copper-based catalysts. On the basis of coordination chemistry, the reduction process of CO 2 is controlled by several steps. These steps include the transfer of two, six, eight and twelve electrons, corresponding to the common products CO, CH 3 OH, CH 4 , C 2 H 4 and C 2 H 5 OH (Table 1).

“…In the oil and natural gas extraction process, associated gas and flare gas are valuable resources. Almost 150–170 billion m 3 yr –1 of gas is flared from production wells to generate 750 billion kWh of electricity, but this process is accompanied by 382 Mt yr –1 of CO 2 emissions and 3 Mt yr –1 of additional CH 4 emissions from unlit flaring. , Although the amounts of emitted CO 2 and CH 4 are minor in comparison to the gross reserves of atmospheric greenhouse gases, it will be beneficial if this part of methane in flare gas could be recovered. Conversions of methane to value-added chemicals provide commercially profitable paths for sustainable utilization of high concentrated methane.…”

With 28−34 times the greenhouse effect of CO 2 over a 100-year period, methane is regarded as the second largest contributor to global warming. Reducing methane emissions is a necessary measure to limit global warming to below 1.5 °C. Photocatalytic conversion of methane is a promising approach to alleviate the atmospheric methane concentrations due to its low energy consumption and environmentally friendly characteristics. Meanwhile, this conversion process can produce valuable chemicals and liquid fuels such as CH 3 OH, CH 3 CH 2 OH, C 2 H 6 , and C 2 H 4 , cutting down the dependence of chemical production on crude oil. However, the development of photocatalysts with a high methane conversion efficiency and product selectivity remains challenging. In this review, we overview recent advances in semiconductor-based photocatalysts for methane conversion and present catalyst design strategies, including morphology control, heteroatom doping, facet engineering, and cocatalysts modification. To gain a comprehensive understanding of photocatalytic methane conversion, the conversion pathways and mechanisms in these systems are analyzed in detail. Moreover, the role of electron scavengers in methane conversion performance is briefly discussed. Subsequently, we summarize the anthropogenic methane emission scenarios on earth and discuss the application potential of photocatalytic methane conversion. Finally, challenges and future directions for photocatalytic methane conversion are presented.

“…[3][4][5][6] Considering the deteriorating environmental conditions and rising health threats, a consensus has been formed on the urgency of atmospheric environmental management with the efforts of all parties, and initial results have been achieved in controlling industrial exhaust emissions. [7][8] At the present stage of industrial exhaust gas treatment, several strategies have been developed for exhaust gas capture and energy conversion, mainly including conventional technologies such as catalytic combustion (RCO), catalytic oxidation, and acid-base neutralization reactions. [9][10][11] The combustible flue gas remains with combustion value and can be used as industrial or residential fuel and heat source for re-utilization.…”

Industrial waste gas emissions from fossil fuel over‐exploitation have aroused great attention in modern society. Recently, metal‐organic frameworks (MOFs) have been developed in the capture and catalytic conversion of industrial exhaust gases such as SO2, H2S, NOx, CO2, CO, etc. Based on these resourceful conversion applications, in this review, we summarize the crucial role of the surface, interface, and structure optimization of MOFs for performance enhancement. The main points include (1) adsorption enhancement of target molecules by surface functional modification, (2) promotion of catalytic reaction kinetics through enhanced coupling in interfaces, and (3) adaptive matching of guest molecules by structural and pore size modulation. We expect that this review will provide valuable references and illumination for the design and development of MOF and related materials with excellent exhaust gas treatment performance.
