By coupling both anodic and cathodic reactions, the system achieves enhanced energy efficiency and scalability, offering a practical and economically viable route toward sustainable plastic upcycling.

Cobalt catalysts are industrial workhorses, producing millions of tons of chemicals annually, a process long believed to require harsh, energy-intensive conditions. Kubis, Liu et al. provide a detailed stability map for these crucial catalysts, demonstrating that they are surprisingly robust and active under significantly milder pressures than conventionally used. This work offers a fundamental blueprint for optimizing large-scale industrial reactions, creating opportunities for significant energy savings and more sustainable chemical production.

Performance-enhancing asymmetric catalysis (PEAC) is a new strategy for catalyst optimization. Rather than relying on the slow, resource- and time-intensive covalent modification of chiral ligands, this approach “tunes” a single ligand by using a library of simple, achiral acids. The counterions produced upon ion-pair formation perturbate the catalyst’s chiral pocket through noncovalent interactions to significantly improve enantioselectivity. This method creates an adaptable chiral ligand system that is well suited for rapid, high-throughput screening and catalyst discovery.

Proton exchange membrane water electrolysis (PEMWE) is vital for green hydrogen, but its scalability is threatened by reliance on scarce iridium. This perspective outlines an integrated iridium management strategy, combining advanced catalyst and component design to drastically reduce iridium use with the establishment of closed-loop recycling systems to process end-of-life catalysts for reuse, thereby establishing a circular economy for iridium. This holistic approach is essential to enable terawatt-scale, sustainable hydrogen production.

This review highlights how in situ Raman spectroscopy elucidates oxygen reduction reaction (ORR) mechanisms. Different enhanced Raman strategies, including shell-isolated nanoparticle-enhanced Raman spectroscopy (SHINERS), the “borrowing” surface-enhanced Raman spectroscopy (SERS) strategy, and tip-enhanced Raman spectroscopy (TERS), have been employed to reveal ORR pathways and intermediates on model and nanocatalysts, such as single crystals, nanocatalysts, and single-atom crystals. These studies provide molecular-level insights into ORR mechanisms and structure-activity relationships for rational catalyst design.

Super-dry reforming of CH4 (SDRM) consumes 1 mol of CH4 to reduce 3 mol of CO2 and produce 4 mol of CO, making it an ideal method for the direct utilization of CO2-rich CH4 streams. This work develops a catalyst-free plasma SDRM process driven by a rotating arc. In the plasma SDRM process, ultra-high temperatures and electric fields promote the forward reaction while sharp temperature gradients suppress the reverse reaction, demonstrating an efficient approach for valorizing CO2-rich CH4 streams.

CO2 reduction is typically carried out in aqueous electrolytes. Non-aqueous systems can suppress hydrogen evolution but increase cell voltages. This techno-economic assessment of non-aqueous CO2 reduction shows that oxalic acid, a two-electron product, could be commercially viable via this process. Oxalic acid would cost $2.87/kg at small scale and $1.56/kg at commercial scale, near current market prices. This levelized cost is dominated by product separation, stack replacement, and electricity costs. We also propose a technical roadmap toward cost-competitive non-aqueous CO2R.

CO2 electrolysis in fully aqueous conditions is currently strongly limited by mass transport of CO2. Fast pressure pulses enhance the mass transport of CO2 substantially, reaching partial current densities >80 mA/cm2. We find that this is due to both vibration of gas bubbles and flow oscillations.
