Photocatalytic oxygen reduction for hydrogen peroxide （H2O2） synthesis presents a green and costeffective production ***,achieving highly selective H2O2synthesis remains challenging,necessitating precise control over free radical reaction pathways and minimizing undesirable oxidative ***,we report for the visible light-driven simultaneous co-photocatalytic reduction of O2to H2O2and oxidation of biomass using the atomic rubidium-nitride modified carbon nitride（CNRb）.The optimized CNRb catalyst demonstrates a record photoreduction rate of 8.01 mM h-1for H2O2generation and photooxidation rate of 3.75 mM h-1for furfuryl alcohol to furoic acid,achieving a remarkable solar-to-chemical conversion （SCC） efficiency of up to 2.27%.Experimental characterizations and DFT calculation disclosed that the introducing atomic Rb–N configurations allows for the high-selective generation of superoxide radicals while suppressing hydroxyl free radical *** is because the Rb–N serves as the new alternative site to perceive a stronger connection position for O2adsorption and reinforce the capability to extract protons,thereby triggering a high selective redox product *** study holds great potential in precisely regulating reactive radical processes at the atomic level,thereby paving the way for efficient synthesis of H2O2coupled with biomass valorization.

A major controversy was sparked worldwide by a recent national water census claiming that the number of Chinese rivers with watersheds ≥100 km2was less than half the previous estimate of 50 000 rivers, which also stimulates debates on the potential causes and consequences. Here, we estimated the number of rivers in terms of stream-segmentation characteristics described by Horton, Strahler and Shreve stream-order rules, as well as their mixed mode for named rivers recorded in the Encyclopedia of Rivers and Lakes in *** a result, the number of ‘vanishing rivers’ has been found to be highly relevant to statistical specifications in addition to the erroneous inclusion of pseudo-rivers primarily generated in arid or frost-thaw areas. The modified Horton stream-order scheme reasonably depicts the configuration of complete natural streams from headwater to destination, while the Strahler largely projects the fragmentation of the named river networks associated with human aggregation to the hierarchical river systems.

This study was undertaken to evaluate the effects of mixing BDC-NO2and BDC-NH2linkers in the synthesis of Zrbased metal organic frameworks(Zr-MOFs) on their adsorption and separation of CO2and CH4. Ui O-66 with single or binary-NO2and-NH2 samples were synthesized under solvothermal conditions and activated by solvent exchanging using methanol. Structural analyses of the materials were conducted using FTIR, XRD, TGA,SEM,1 HNMR and N2 adsorption/desorption techniques and adsorption of CO2and CH4at high pressures and different temperatures(273 and 298 K) was investigated. It was found that Ui O-66-NH2 exhibited higher CO2and CH4adsorption capacities than those of Ui O-66-NO2. Addition of-NH2functional group in Ui O-66-NO2could enhance CO2and CH4adsorption due to the extra CO2adsorption sites of-NH2functional groups. Addition of-NO2functional group to Ui O-66-NH2 at a low loading could also increase CO2and CH4adsorption, however,a high loading of NO2functional group to Ui O-66-NH2 would result in decreased adsorption.

城市固体废弃物(municipal solid waste,MSW)的燃烧依次经历干燥和热解、挥发分燃烧、焦炭燃烧三个阶段,描述样品热解、燃烧动力学特性的主要参数包括样品质量、温度、尺寸和点火特性等。实际固废焚烧处理过程的主要特征包括升温速率高(400 K/min以上)、样品尺寸大、组分复杂和样品体积收缩等。然而,常规用于测量固废热解、燃烧的实验设备如TGA、macro TGA和沉降炉等存在升温速率或样品尺寸受限、难以同时获取样品的质量和温度及图像信息等缺陷。为此,搭建了可视化大尺寸快速升温热重分析装置,测量了打印纸、PET塑料、松木和厨余垃圾及其混合样品在慢速升温(10 K/min,15 K/min,25 K/min)和快速升温(约500 K/min)工况下热解和燃烧的质量、温度和图像信息。结果表明:升温速率对混合样品的热解和燃烧动力学特性影响较大。慢速升温模式下,混合样品燃烧DTG曲线呈现多峰特征,且这些峰的出现时间与其四种组分的燃烧DTG曲线峰值具有对应关系;快速升温模式下,混合样品各组分的热解区间趋于重叠,燃烧DTG曲线的峰减少为一个。温度和图像信息表明,15 K/min慢速升温模式下,混合样品内部和表面的点火时间基本一致,点火时样品中心温度为191℃,燃烧发生在样品表面。快速升温模式下,升温开始后样品表面可以立即观察到挥发分的燃烧火焰,随后燃烧逐步向样品内部扩展。随着燃烧的进行,样品尺寸持续收缩,直至燃尽。
