Supporting data for "Protons Buffer at Cathode via Al3+(H2O)6 Hydrolysis for Enhancing Electrochemical Reduction: Examples of Bismuth-Oxychloride Storage Battery and Carbon Dioxide Conversion"

The hydrogen evolution reaction (HER) is an undesirable cathodic reaction in aqueous electrochemical technologies such as carbon dioxide reduction (ERCO2) and bismuth-based electrode discharge in storage batteries. Most aqueous electrochemical systems are either acidic or alkaline media which promote the unwanted HER. This thesis aims at deploying Al3+(H2O)6 buffered aqueous electrolyte to facilitate the reduction of BiOCl electrode and ERCO2 with improvement in energy efficiency.

氢析出反应（HER）是水溶液电化学技术中如二氧化碳还原（ERCO2）和基于铋电极的电池放电过程中的一种不希望发生的阴极反应。大多数水溶液电化学系统要么为酸性，要么为碱性介质，这些介质会促进不希望的HER。本论文旨在采用Al3+(H2O)6缓冲水溶液电解质，以促进BiOCl电极和ERCO2的还原，并提高能源效率。
