| 1 | Bimetallic nickel molybdate supported Pt catalyst for efficient removal of formaldehyde at low temperature显示文摘Efficient removal of formaldehyde from indoor environments is of significance for human health.In this work,a typical binary transition metal oxide that could provide various oxidation states,β-NiMoO4,was employed as a support to immobilize the active Pt component(Pt/NiMoO4)for catalytic formaldehyde elimination at low ambient temperature(15℃).The results showed that the hydrothermal preparation temperature and time had a noticeable impact on the morphology and catalytic activity of the samples.The catalyst prepared with hydrothermal temperature of 150℃for 4 hr(Pt-150-4)exhibited superior catalytic activity and stability mainly due to its distinctly porous structure,relative abundance of adsorbed surface hydroxyls/water,and high oxidation ability,which resulted from the interaction of Pt with Ni and Mo of the bimetallic NiMoO4 support.Our results might shed light on the rational design of multifunctional catalysts for removal of indoor air pollutants at low ambient temperature. | Gang Huang Zhaoxiong Yan Shuyuan Liu Tingting Luo Liang An Zhihua Xu | 2020 | Journal of Environmental Sciences2020，32，1： | 6 |

| 3 | Room-temperature conversion of ethane and the mechanism understanding over single iron atoms confined in graphene显示文摘The catalytic conversion of ethane to high value-added chemicals is significantly important for utilization of hydrocarbon resources.However, it is a great challenge due to the typically required high temperature(> 400 ℃) conditions.Herein, a highly active catalytic conversion process of ethane at room temperature(25 ℃) is reported on single iron atoms confined in graphene via the porphyrin-like N4-coordination structures.Combining with the operando time of flight mass spectrometer and density functional theory calculations, the reaction is identified as a radical mechanism, in which the C–H bonds of the same C atom are preferentially and sequentially activated, generating the value-added C2 chemicals, simultaneously avoiding the over-oxidation of the products to CO2.The in-situ formed O–FeN4–O structure at the single iron atom serves as the active center for the reaction and facilitates the formation of ethyl radicals.This work deepens the understanding of alkane C–H activation on the FeN4 center and provides the reference in development of efficient catalyst for selective oxidation of light alkane. | Suheng Wang Haobo Li Mengqi He Xiaoju Cui Lei Hua Haiyang Li Jianping Xiao Liang Yu N.Pethan Rajan Zhaoxiong Xie Dehui Deng | 2019 | Journal of Energy Chemistry2019，28，9： | 1 |

| 5 | Analysis on Hydrogeochemical Characteristics and Their Temporal and Spatial Variation in the Karst Catchment of Lianjiang River,Northern Guangdong Province显示文摘[Objective]The study aimed to discuss the hydrogeochemical features and their temporal and spatial variation in the karst catchment of Lianjiang River,northern Guangdong Province.[Method]Water samples were collected from 10 sub-drainages of Lianjiang River in July of 2012and January of 2013,and then major chemical ions in tributaries of Xingzi River and Tongguanshui River were analyzed in detail to discuss the hydrochemistry type,spatial and temporal distribution and its causes of formation in Lianjiang River basin.[Result]Among chemical ions in the water samples,Ca^(2+)and HCO_3^-were dominant in Lianjiang River,accounting for over 70%and 80%of total concentrations of cations and anions respectively,followed by Mg^(2+)and SO_4^(2-).The concentrations of most major ions were higher in winter than those in summer except SO_4^(2-)concentration was much higher in summer than that in winter,which was related to anthropogenic factors.From hydrochemical types,it is seen that HCO_3^--Ca^(2+)type in summer and HCO_3^--Ca^(2+)?Mg^(2+)type in winter were dominant in Lianjiang River,followed by the HCO_3^--SO_4^(2-)?Ca^(2+)type,and only two samples of Xingzi River belonged to HCO_3^--Ca^(2+)?Mg^(2+)?Na^+type in winter.The spatial distribution regularity of chemical ions was not obvious in the 10 sub-drainages of Lianjiang River.The concentrations of chemical ions changed greatly in the upper reaches but slightly in the lower reaches of Xingzi River catchment.The concentrations of chemical ions were steady in Tongguanshui River catchment with a smaller area,and it was a little higher in the upper reaches than those in the lower reaches.[Conclusion]Natural processes,such as lithological heterogeneities and atmospheric precipitation,contributed to the chemical composition of Lianjiang River catchment,northern Guangdong Province. | Zhou Chen Xizhi Wang Baosheng Li Gongcou Guan Zhaoxiong Liang Jun Wang | 2013 | Meteorological and Environmental Research2013，4，11： | 0 |
