Solar-driven catalytic conversion of carbon dioxide (CO2) into value-added C2+ chemicals and fuels has attracted significant attention over the past decades, propelled by urgent environmental energy demands. However, reduction CO2 continues to face challenges due inherently slow kinetics. This review traces historical development current state photothermal reduction, detailing mechanisms which is transformed products. A key focus on catalyst design, emphasizing surface defect engineering, bifunctional active site co-catalyst coupling enhance efficiency selectivity solar-driven synthesis. Key reaction pathways both C1 products are discussed, ranging from CO, CH4 methanol (CH3OH) synthesis production C2-4 such as hydrocarbons, ethanol, acetic acid, various carbonates. Notably, advanced C5+ hydrocarbons exemplifies remarkable potential technologies effectively upgrade CO2-derived products, thereby delivering sustainable liquid fuels. provides a comprehensive overview fundamental mechanisms, recent breakthroughs, pathway optimizations, culminating in valuable insights for future research industrial-scale prospect reduction.

Boosting CO₂ photoreduction by creating electron mediator in carbon‐enriched poly(heptazine imide)

AIChE Journal, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 17, 2025

Abstract The insufficient light absorption capacity and severe photogenerated carrier recombination limit the overall efficiency of photocatalysts. Herein, we designed carbon‐rich poly(heptazine imide) (PHI) by copolymerization melamine 2,4,6‐triamine‐pyrimidine with KCl/KI. This material has been demonstrated to markedly enhance utilization rate photons while simultaneously optimizing charge electrons. PHI showed a higher CO₂ reduction than PHI, CO generation reaching 46.6 μmol g −1 h . To overcome obstacle slow mass transfer, flow reactor was in‐house. yield on in home‐built found be as high 153 , which is 3.3 times that observed batch reactor. findings experimental study are alignment results theoretical modeling, based finite volume analysis method.

Active learning streamlines development of high performance catalysts for higher alcohol synthesis

Nature Communications, Journal Year: 2024, Volume and Issue: 15(1)

Published: July 11, 2024

Developing efficient catalysts for syngas-based higher alcohol synthesis (HAS) remains a formidable research challenge. The chain growth and CO insertion requirements demand multicomponent materials, whose complex reaction dynamics extensive chemical space defy catalyst design norms. We present an alternative strategy by integrating active learning into experimental workflows, exemplified via the FeCoCuZr family. Our data-aided framework streamlines navigation of composition condition in 86 experiments, offering >90% reduction environmental footprint costs over traditional programs. It identifies Fe
