Piezo-electrocatalysis based on the non-centrosymmetric materials opens an avenue for mechano-to-H2 production through harvesting mechanical energy, being undergoing significant growth. Direct comparison of performance various piezo-electrocatalysts is necessary to obtain optimal candidates satisfying demands practical application but remains a grand challenge because acquiescently added sacrificial agents vary considerably in literature. Herein, we systematically investigate effect four commonly used types containing totally 15 piezo-electrocatalytic hydrogen evolution by choosing typical BaTiO3 catalyst as demo. It found that pH, length carbon chain, adsorption strength between catalysts and agent, combination would impact H2 performance. Moreover, self-decomposition agent-water mixtures under ultrasonic vibration, implying can be generated without piezo-electrocatalysts, which was usually ignored. Thus, this work, concept net yield suggested standardize evaluation future.

Electrocatalytic reduction of carbon dioxide into value-added chemical fuels is a promising way to achieve neutrality. Bismuth-based materials have been considered as favorable electrocatalysts for converting formic acid. Moreover, size-dependent catalysis offers significant advantages in catalyzed heterogeneous processes. However, the size effects bismuth nanoparticles on acid production not fully explored. Here, we prepared Bi uniformly supported porous TiO2 substrate electrocatalytic by situ segregation element from Bi4Ti3O12. The Bi-TiO2 electrocatalyst with 2.83 nm displays Faradaic efficiency greater than 90% over wide potential range 400 mV. Theoretical calculations also demonstrated subtle electronic structural evolutions induced variations nanoparticles, where display most active p-band and d-band centers guarantee high electroactivity toward CO2RR.
