【 摘 要 】

tsWater-dispersible CsPbBr3 nanocrystals (NCs) exhibit ultra-stability (>200 days) in water with only ~20% decline of the initial photoluminescence intensity.The as-prepared ultra-stable water-dispersible CsPbBr3 NCs showed high electrocatalysis activity (faradaic yield: 32% for CH4, 40% for CO) and operation stability (>350 h) for CO2 reduction reaction.
