Abstract: Novel metal catalysts are easily poisoned by CO adsorption or leaching in oxidation of formic acid that leads to decrease the performances of catalyst. To increase the catalyst activity and poison tolerance in fuel cells, novel metal nanoparticles are usually supported on modified support materials to enhance its performance. In this study, TiO2/MWCNTs are synthesized by sol-gel method. Also, ammonium is used to dope nitrogen into TiO2 to modify its electrical and chemical property. MWCNTs, TiO2/MWCNTs and N-doped TiO2/MWCNTs are three supporters using in this study to examine the effects of supporters on the electrocatalytic performance of Pd and AuPd catalysts. The synthesized metal nanoparticles are uniformly dispersed on the surfaces of MWCNTs, TiO2 and N-doped TiO2 modified MWCNTs. The electrochemical analysis illustrate that Pd/N-doped TiO2/MWCNTs (molar ratio of NH4OH:TiO2=4:1) catalyst exhibits higher activity and better stability than that of Pd/MWCNTs either/or Pd/TiO2/MWCNTs

Abstract: Water use across various sectors in India is on the rise. Delhi being the capital city of the country attracts lots of migrant population which resulting pressure on required infrastructure particularly demand of water. Delhi as a capital city have rapidly expanding centre of government, trade, commerce and industry, therefore, it is an instructive location for studying the water recycles options by hospitality sector. In Delhi city there are about 37 five star hotels, 20 four star hotels and 44 resorts/motels. The hospitality industry consumes a large quantity of fresh water to provide and maintain hygiene and recreational standards as per guests’ expectations. The Delhi city has been experiencing severe water scarcity in terms of supply and demand for a very long time. It is getting worse day by day due to increasing demand of water with the economic liberalization and globalization. This paper presents an estimate of water consumption and thereby analyzing the reuse potential by the
