Volume 13, Issue 3 , July 2022


  Doping of cations into wide bandgap semiconductors is an effective method of increasing photocatalytic activity. This work aims to find out how dopant ions like Ag+, Cu2+ and Sn2+ affect the structural, optical and photocatalytic properties of Li2GeTeO6. The parent Li2GeTeO6 (LGTO) was synthesized by ...  Read More

Electrochemical Hydrogen Evolution Reaction Triggered by Co2xMo1-xS2 (x = 0. 0.05 and 0.1) in Acidic Medium

Aruna K Kunhiraman; Bradha Madhavan

Volume 12, Issue 8 , August 2021, , Pages 1-4


  Facile solvothermal route was adopted for the synthesis of Co2xMo1-xS2 with x = 0, 0.05 and 0.1. Higher HER activity was exhibited by x = 0.1 in Co doped MoS2, with a current density -140 mAcm -2 at an overpotential of -100 mV. At lower overpotential both the compositions exhibited almost same activity, ...  Read More

Mannepalli Sudheera; Perala Venkataswamy; Gundeboina Ravi; Kadari Ramaswamy; Nalluri Chitti Babu; Muga Vithal

Volume 12, Issue 4 , April 2021, , Pages 1-10


  Anion doping is one of the efficient ways to tailor the bandgap of photocatalysts for the treatment of polluted water. The present work describes the improved photocatalytic activity of defect pyrochlore, KTaTeO6 (KTTO), upon nitrogen doping, towards the degradation of methylene blue under visible light ...  Read More

Graphene and doped graphene: A comparative DFT study

Jyoti Tyagi; Lekha Sharma; Rita Kakkar

Volume 10, Issue 7 , July 2019, , Pages 484-490


  Two different models, ovalene (C32H14) and circumcoronene (C54H18) and their respective doped models (C31XH14, C53XH18 where X = B, Al, N, P, Fe, Ni and Pt) have been considered for DFT calculations at the GGA-PBE/DNP level. The two models are compared on the basis of various calculated structural parameters ...  Read More

  Co and In co-doped nanopowders of ZnO as well as In and Co singly doped ZnO were successfully prepared using sol-gel method. The synthesized samples were characterized using x-ray diffraction (XRD), UV-vis spectroscopy (UV-vis), Raman spectroscopy (RS), Transmission Electron Microscopy (TEM) and Energy ...  Read More

A First-principle Study Of The Optical Properties Of Pure And Doped LaNiO3

Tarun Kumar Kundu; Debolina Misra

Volume 7, Issue 5 , May 2016, , Pages 344-348


  Density Functional Theory (DFT) is employed to study the various optical properties of pseudo-cubic LaNiO3. As LaNiO3 is a strongly correlated material, conventional DFT like LDA or GGA and even GW approximation fail to describe, we have examined the optical spectra of this compound using GGA(PBE)+U ...  Read More

Electrical And Microstructural Properties Of (Cu, Al, In)-doped SnO2 Films Deposited By Spray Pyrolysis

Sibel Gurakar; Tulay Serin; Necmi Serin

Volume 5, Issue 6 , June 2014, , Pages 309-314


  The effect of Cu, Al and In doping on the microstructural and the electrical properties of the SnO2 films were studied. The undoped, Cu, Al and In (2 at. %) doped SnO2 films were deposited on the glass substrate by spray pyrolysis from 0.8 M SnCl2–ethanol solution at substrate temperature 400 °C. ...  Read More
