| 1 | N-doped mesoporous alumina for adsorption of carbon dioxide显示文摘N-doped mesoporous alumina has been synthesized using chitosan as the biopolymer template. The adsorbent has been thoroughly investigated for the adsorption of CO2 from a simulated flue gas stream (15% CO2 balanced with N2 ) and compared with commercially available mesoporous alumina procured from SASOL, Germany. CO2 adsorption was studied under different conditions of pretreatment and adsorption temperature, inlet CO2 concentration and in the presence of oxygen and moisture. The adsorption capacity was determined to be 29.4 mg CO2 /g of adsorbent at 55°C. This value was observed to be 4 times higher in comparison to that of commercial mesoporous alumina at a temperature of 55°C. Basicity of alumina surface coupled with the presence of nitrogen in template in synthesized sample is responsible for this enhanced CO2 adsorption. Adsorption capacity for CO2 was retained in the presence of oxygen; however moisture had a deteriorating effect on the adsorption capacity reducing it to nearly half the value. | Jayshri A.Thote Ravikrishna V.Chatti Kartik S.Iyer Vivek Kumar Arti N.Valechha Nitin K.Labhsetwar Rajesh B.Biniwale M.K.N.Yenkie Sadhana S.Rayalu | 2012 | Journal of Environmental Sciences2012，24，11： | 1 |
| 2 | 环境催化中的陶瓷材料:应用与可能性(英文)显示文摘Environmental catalysis has been steadily growing because of the advances in its scientific and engineering aspects,as well as due to the new environmental challenges in the industrial era.The development of new catalysts and materials is essential for new technologies for various environmental applications.Ceramics play important roles in various environmental applications including the identification,monitoring,and quantification of pollutants and their control.Ceramics have important applications as sensors and photocatalysts,and they are extensively used as catalyst carriers and supports.Many ceramics are being explored as catalysts for pollution control applications.Their low cost,thermal and chemical stability,and capability of being tailored make them especially attractive for pollution control applications.Although a wide variety of materials have been developed as catalyst supports,this area is still of interest with new or modified catalyst supports being frequently reported.It is of equal importance to develop new or modified processes for the loading of catalysts on specific supports.Applications like chemical looping combustion(CLC) and other catalytic combustion processes are raising the demands to a new scale.We have been working on the development of both new and modified support materials,including mesoporous materials without structural order for possible applications in CLC and other catalytic reactions.Successful attempts have been made in the modification of conventional γ-Al2O3 and improved synthesis processes for supporting perovskite type catalysts.Our research on environmental catalysis applications of ceramic materials and processes are also briefly discussed. | Nitin LABHSETWAR P.DOGGALI S.RAYALU R.YADAV T.MISTUHASHI H.HANEDA | 2012 | 催化学报2012，33，10： | 1 |
