Effective removal of environmental pollutants relies heavily on advanced reduction processes (ARPs), and developing effective low cost catalysts is pivotal. Herein, we demonstrate that cobalt phthalocyanine (CoPc) adsorbed nitrogen-doped mesoporous carbon (NMC) can serve as an efficient catalyst for ARPs. The CoPc-NMC composite stands out its remarkable ability to reduce hexavalent Cr(VI) using formic acid the reducing agent. This exceptional performance attributed distinct characteristics composite, including atomically dispersed CoPc strong π-π interactions with rich pyridinic N-doped support. Our research also reveals complex involvement active species, such electrons hydrogen radicals, which clarifies mechanism behind this catalytic process. Ultimately, study not only sheds light factors influence activity but offers critical insights into more strategies in applications.

Abstract A concept of combining photocatalytically generated hydrogen with green enzymatic reductions is demonstrated. The developed photocatalytic formic acid (FA) dehydrogenation setup based on Pt(x)@TiO 2 shows stable generation activity, which two orders magnitude higher than reported values state‐of‐the‐art systems. Mechanistic studies confirm that proceeds via a pathway, entirely different from purely thermal reaction mechanisms previously reported. viability the presented approach demonstrated by synthesis value‐added compounds 3‐phenylpropanal and (2 R , 5 S )‐dihydrocarvone at ambient pressure room temperature, should be applicable for many other hydrogenation processes, e. g., preparation flavours fragrance compounds, as well pharmaceuticals.

Abstract The single‐atom M‐N‐C (M typically being Co or Fe) is a prominent material with exceptional reactivity in areas of catalysis for sustainable energy. However, the formation metal nanoparticles materials coupled high‐temperature calcination conditions, limiting density M‐N x active sites and thus restricting catalytic performance such catalysts. Herein, we describe an effective decoupling strategy to construct high‐density by generating polyfurfuryl alcohol MOF precursor, effectively preventing even up 6.377% cobalt loading. This catalyst showed high H 2 production rate 778 mL g Cat −1 h when used dehydrogenation reaction formic acid. In addition site, curved carbon surface structure also thought be reason catalyst.
