The abused ciprofloxacin antibiotics have caused significant environmental *** oxidative degradation of ciprofloxacin exhibits promising efficacy,it often entails excessive energy ***,it is necessary to explore an effective and ecologically sustainable degradation ***,we demonstrated that g-C_(3)N_(4) decorated with the coordinated CeO_(2)and Co_(3)O_(4)(CeO_(2)-Co_(3)O_(4)/CN)exhibited effective ciprofloxacin photodegradation via in situ H_(2)O_(2) production and activation *** indicate that the introduced CeO_(2) enhances the transference of photogenerated electrons to O_(2) by adjusting the oxygen vacancy of photocatalyst,thereby increasing the generation of superoxide radicals,which in turn generate H_(2)O_(2),resulting in a 22.4-fold increase in H_(2)O_(2) generation over g-C_(3)N_(4).Moreover,the in situ H_(2)O_(2)generation facilitated by CeO_(2) is confirmed to be essential for ciprofloxacin degradation via CeO_(2)-Co_(3)O_(4)/CN,as it provides enough oxidant for Co_(3)O_(4) to activate into hydroxyl radicals for the pollutants ***,CeO_(2)-Co_(3)O_(4)/CN achieves a ciprofloxacin degradation ratio of 97.7%within 80 *** study introduces a novel approach that combines H_(2)O_(2) generation and activation,offering an innovative perspective for achieving clean and efficient purification of antibiotic-contaminated water.

自然环境下的植被群落,由于各种群之间以及种群与环境间的竞争与选择,常呈现出一定的垂直结构,对于同一植株的不同生长阶段,在垂直方向也有着不同的生理生化参数。对这种三维立体分布特征进行探测,能够进行生态环境立体化定量评价,对森林碳储量估算和生物多样性保护等具有重要意义。传统的被动光学遥感以及激光雷达在植被生化参数垂直探测方面有较大的局限性,而高光谱激光雷达(Hyperspectral LiDAR,HSL)这一新型探测仪器的出现为探测植被生理生化参数垂直分布提供了新的手段。但由于受到硬件方面的限制,HSL在机载平台下对森林复杂立体场景的适用性尚未得到充分研究。故首先基于HSL原型样机在实验室开展小尺度的室内测量,以火炬花植株为目标,验证其对空间信息和光谱信息的一体化提取能力;随后进一步使用三维辐射传输模型构建具有垂直异质性特征的森林场景,模拟机载HSL设备实现森林的高光谱三维点云提取,结合植被指数和随机森林模型对场景中三种不同植被冠层的叶绿素浓度和类胡萝卜素浓度进行反演。结果表明:室内实验证实了HSL回波信息可以有效区分植株不同高度处光谱曲线的差异,火炬花上部红色叶片和下部绿色叶片的归一化植被指数分别小于和大于0.5;基于三维辐射传输模型成功构建了虚拟森林场景的机载HSL高光谱三维点云,在得到的24组植被指数中,有17组指数表现出良好的探测精度(平均绝对百分比误差MAPE<13%);植被叶绿素反演模型R^(2)达到0.93,上层、中层和下层的平均绝对误差MAE分别为6.26、3.40和2.81;类胡萝卜素反演模型R^(2)为0.91,上层、中层和下层的MAE分别为1.59、2.58和0.39。该研究显示出HSL设备是一种立体化提取植被光谱信息的有效手段,在探测森林等复杂植被场景的生化组分垂直分布方面具有巨大的应用潜力。

在“碳达峰、碳中和”战略目标引领下,绿色创新成为了重污染企业实现高质量发展的关键。环保补助作为政府激励性环境规制工具对不同社会责任水平企业的绿色创新会产生不同的激励效果。基于波特假说、利益相关者理论和制度理论,采用面板门槛回归模型,以2010-2019年337家重污染行业上市公司为样本,探索并验证环保补助对企业绿色创新的影响差异及内在机制。研究发现:环保补助对绿色创新的激励效果主要奏效于跨过企业社会责任门槛的企业。并且,当企业社会责任累积跨过门槛后,环保补助对企业绿色创新的激励效果在国有企业中效果更好。
