Glycerol(electrochemical) oxidation reaction(GOR) producing organic small molecule acid and coupling with hydrogen evolution reaction is a critical aspect of ensuring balanced glycerol capacity and promoting hydrogen generation on a large scale. However, the development of highly efficient and selective non-noble metal-based GOR electrocatalysts is still a key problem. Here, an S-doped CuO nanorod array catalyst(S-CuO/CF) constructed by sulfur leaching and oxidative remodeling is used to drive GOR at low potentials: It requires potentials of only 1.23 and 1.33 V versus RHE to provide currents of 100 and 500 mA cm^(-2), respectively. Moreover, it shows satisfactory comprehensive performance(at 100 mA cm^(-2), V_(cell) = 1.37 V) when assembled as the anode in asymmetric coupled electrolytic cell. Furthermore, we propose a detailed cycle reaction pathway(in alkaline environment) of S-doped CuO surface promoting GOR to produce formic acid and glycolic acid. Among them, the C–C bond breaking and lattice oxygen deintercalation steps frequently involved in the reaction pathway are the key factors to determine the catalytic performance and product selectivity. This research provides valuable guidance for the development of transition metal-based electrocatalysts for GOR and valuable insights into the glycerol oxidation cycle reaction pathway.

Summary of main observation and conclusion There are active debates on whether the concept of aromaticity should be exte nded bey ond carb on based organic systems. One argument against such extension is that the proposed new aromatic species are not bottleable. We present herein in-depth chemical bonding analyses of a synthetic, core-shell, intermetalloid [Pd3Sn8Bi6]^4-.cluster. The computational data unravel unprecedented five-fold (π and σ) aromaticity, in cludi ng d-orbital aromaticity. Delocalized electr on clouds in this all-metal system cover the Pd3 core, trigonal pyramid Sn4 caps, peripheral Bi6 ring, and roof-like Sn2Bi2 walls, each following the (4n+2) Huckel rule. The present finding is beyond imagination, providing a compelling example that all-metal aromaticity not only exists in bulk compounds, but also can be in multifold π/σ fashion.
