Natural fibrils derived from biomass were used as a template to synthesize uniformly decorated nanoparticles (10-12 nm) of molybdenum carbide (MoC) and molybdenum nitride (MoN) supported on carbon. The nanoparticles have been synthesized through the carburization and nitridation of molybdenum on cotton fibrils, using a high-temperature solid-state reaction. The catalyst exhibits an onset potential of 110 mV and an overpotential of 167 mV to derive a cathodic current density of 10 mA cm. The electrocatalyst also demonstrates excellent long-term durability of more than 2500 cycles in acidic media with a Tafel slope value of 62 mV dec.
源自生物质的天然纤维被用作模板，以合成均匀负载在碳上的碳化钼（MoC）和氮化钼（MoN）纳米颗粒（10 - 12纳米）。通过在棉纤维上对钼进行渗碳和氮化反应，利用高温固态反应合成了这些纳米颗粒。该催化剂在产生10 mA cm的阴极电流密度时，起始电位为110 mV，过电位为167 mV。该电催化剂在酸性介质中还表现出超过2500次循环的出色长期耐久性，塔菲尔斜率值为62 mV dec。
