Abstract The use of methanol as a chemical precursor and fuel additive has increased recently on global scale. Hence, this study combined bibliometric traditional review methods to assess the recent trends evolution production, well its use. According study, producing large scale from renewable sources is still hampered by immature technologies used in production. For instance, production via process biochemical conversion remains at laboratory level even though it proven be promising option. Cu-based catalysts, especially Cu-Zn-based were found most frequently catalysts for hydrogenation CO 2 due their superior activity. shows an annual growth rate 3.63% research within last decade, with 867 authors involved. China leads globally consumption research. highest collaboration occurred between United States America frequency six. proposed future directions, including evaluation environmental impact methanol, focusing entire life cycle, comparing approaches, streamlining procedures. It also recommended conduct flow chemistry novel reactor designs that enhance mass heat transfer catalytic reactors. Graphical

The Paris Agreement was aimed at reducing the global temperature to no more than 2ºC while continuing efforts keep it 1.5 ºC combat climate change and its detrimental effects. Scientists are confident ever that damage already being caused by impacts will get worse as warming progresses, with increasing adverse effects on human health, ecosystems, economies. Therefore, alleviate anthropogenic emissions of carbon dioxide (CO2) into atmosphere, capture, utilisation storage (CCUS) is considered most urgent viable approach. This work studied extensively likely sources CO2 emissions, via or non-anthropogenic; current trends in technology mitigate CO2. Also, provides an extensive discussion sequestration briefly discusses possible By combining benefit direct capturing utilization, long-term storage, CCUS thus appealing profitable idea for meeting reduction targets.

Methanol has been widely used in organic synthesis and fuel fields. The capture selective reduction of CO2 to methanol can not only decrease concentrations but also produce as a value-added chemical fuel. Herein, the via hydrosilylation was reported be accelerated by porphyrinic metal–organic framework (Ir-PCN-222). Catalytic results showed that Ir-PCN-222 efficient for reduction. Under atmospheric pressure, turnover frequency up 157 h–1 number could reach 1875 with catalyst. catalytic reactions accomplished under low concentration (15% 85% N2) more than 99% conversion selectivity. reaction mechanism studied density functional theory calculations molecular dynamics simulations, revealing balance between hydrosilanes around catalytically active iridium porphyrin units confined spaces played an important role product
