Ultrasmall and monodisperse sulfur nanoparticle (S-NP) intercalated CoAl-layered double hydroxide (CoAl-LDH) electrocatalyst exhibits an excellent electrocatalytic activity towards water oxidation with a low overpotential of 250 mV at a high current density of 7.9 mA cm-2 and a Tafel slope of 61 mV dec-1 at the neutral pH condition. The fabrication strategy to achieve a high-performance, robust and durable electrocatalyst is a scale-up in next generation renewable energy fields.
超小且单分散的硫纳米颗粒（S-NP）插层钴铝层状双氢氧化物（CoAl-LDH）电催化剂在中性pH条件下对水氧化表现出优异的电催化活性，在7.9 mA cm-2的高电流密度下过电位低至250 mV，塔菲尔斜率为61 mV dec-1。实现高性能、稳健且耐用的电催化剂的制备策略是下一代可再生能源领域的一个扩大规模的方向。
