我们报道了一种通过六方有序介孔/结晶磷酸锡（mesoSnPi）纳米片与氧化石墨烯（GO）薄层杂交的一锅合成策略，用于生产高效的氧还原反应（ORR）电催化剂。在电催化测试中，获得的纳米复合材料（SnPi@GO）对ORR的电催化性能优于介孔磷酸锡（mesoSnPi）、散装磷酸锡（bulkSnPi）、散装氧化锡（bulkSnO）、各种过渡金属磷酸盐纳米材料和大多数最先进的锰氧化物。
We report a one-pot synthetic strategy for the production of an efficient oxygen reduction reaction (ORR) electrocatalyst by the hybridization of hexagonally ordered mesoporous/crystalline tin phosphate (mesoSnPi) nanoflakes with thin layers of graphene oxide (GO). In the electrocatalytic measurements, the obtained nanocomposite (SnPi@GO) exhibited a superior electrocatalytic performance for ORR over mesoporous tin phosphate (mesoSnPi), bulk tin phosphate (bulkSnPi), bulk tin oxide (bulkSnO), various transition metal phosphate nanomaterials and most state-of-the-art manganese oxides.
