金属纳米材料由于其自身优异的催化性能成为电化学催化剂发展最为迅速的一类催化材料,贵金属催化剂的性能尤为明显。本文利用湿化学法合成了粒径为(8.26±0.2)nm AuPd双金属纳米材料,并与多壁碳纳米管进行复合获得AuPd/CNT复合材料,以此作为敏感材料构建了电化学传感器。Au为主催化剂,Pd为助催化剂,双金属催化剂的协同作用有效地提升了催化性能。以AuPd双金属纳米材料构建的电化学传感器对对乙酰氨基酚(PA)的定量测定具有宽的线性范围(4~1000μmol/L)、低的检测限(0.05μmol/L)。将传感器用于感冒片剂中对乙酰氨基酚的定量测定取得满意的结果,表明AuPd双金属纳米材料在构建电化学传感器用于PA检测中具有良好的应用前景。

Common wheat(Triticum aestivum L.,2n=6x=42,AABBDD)is one of the most widely grown crops worldwide,providing about 20%of the daily calories and protein consumed by humans(Shiferaw et al.,2013).The world population is projected to reach 9.8 billion in 2050(https://***/en/desa/world-population-projectedreach-98-billion-2050-and-112-billion-2100);thus,to meet the challenges of global food and nutritional security,wheat yields must continue to be increased through breeding programs and improved agricultural techniques(Hunter et al.,2017).

随着减排要求日益强烈,排放限制已成为排放依赖型企业生产策略制订的重要约束。基于报童模型分析框架,分别在强制减排政策和限额交易减排政策的约束下,建立了企业期望利润最大化的优化模型。根据两种政策下企业最优产量决策和最大期望收益的比较发现,尽管限额交易减排政策一方面降低了企业的产量,同时减少排放量,但并未相应地减少企业的期望收益。
