摘　　要：燃料电池作为一种新型的能源利用装置,具有能量转化率高,环境污染轻微,易于制备等优点,葡萄糖可作为燃料电池理想的能量来源。通过水热法与退火相结合的方式,在碳布上直接生成具有纳米片阵列结构的镍钼氧化物,并将其作为燃料电池的阳极。通过多种检测手段分析了材料的结构、成分及其对葡萄糖的氧化催化性能,比较了反应溶液中不同镍钼比例对材料性能的影响,找出了最优的材料制备条件(溶液中镍钼比例为1∶1),在0.1 mol/L的KOH和5 mmol/L的葡萄糖底液中可获得的最大功率密度为476.4μW/cm^(2)。As an emerging energy utilization device,the fuel cell offers several advantages including high energy conversion efficiency,minimal environmental pollution,and ease of preparation.Glucose serves as a promising energy source for fuel cells.In this study,nickel-molybdenum oxides with a nanosheet array structure were synthesized directly on carbon cloth using a combination of hydrothermal synthesis and annealing techniques,and subsequently employed as anodes in fuel cells.The structural and compositional attributes of these materials,along with their catalytic properties for glucose oxidation,were thoroughly analyzed.The influence of different Ni∶Mo ratios in solutions on the performance was also assessed.Optimal material preparation conditions were determined to be a ratio of Ni∶Mo=1∶1 in the solution.Under these conditions,the maximum power density of 476.4μW/cm^(2) was achieved in a solution of 0.1 mol/L KOH and 5 mmol/L glucose.
