Electrocatalytic production of hydrogen peroxide enabled by post-synthetic modification of a self-assembled porphyrin cube

Abstract

A self-assembled porphyrin cube can be metalated/transmetalated to contain fourteen cobalt ions in two different environments. The Co(ii) metalloporphyrin sites are electrocatalytically active to selectively generate hydrogen peroxide from oxygen.

Cavity-Shape-Dependent Divergent Chemical Reaction inside Aqueous Pd6L4 Cages

“…Metal–organic cages have also been used as hosts for carrying out different organic reactions. , The reactions investigated include the Diels–Alder reaction, the Knoevenagel condensation, the Nazarov cyclization, the aza-Darzens Reaction, oxidation reactions − and many more. − However, although quite a few reactions inside metal–organic hosts are known, many of them face multiple complications, like product inhibition and cage degradation by the products . Probably for these reasons, most reactions inside cages are single-step; and multiple-step, cascade, or domino reactions are rare. , Similarly, cage dependent divergent reactions, other than regioselective ones, , are also unexplored inside cages.…”

Phosphorus doped hierarchical porous carbon: an efficient oxygen reduction electrocatalyst for on-site H2O2 production

“…5 However, the multi-step reactions and complex separation/concentration processes involved not only lead to energy-extensive consumption, 6 but also use and/or produce varieties of organic solvents, resulting in increased cost and environ-mental pollution. 7 Furthermore, the use of high-pressure H 2 in the synthetic process also increases the risk of explosion. 8 It must be mentioned that the storage and transportation of large quantities of concentrated and highly active H 2 O 2 is also a potential danger.…”
