| 1 | 用于太阳光光催化降解溴化乙锭的高活性锆掺杂锐钛矿型二氧化钛催化剂的制备和表征(英文)显示文摘Ethidium bromide is a fluorescent tag and is used in biomedical applications.It is a potent mutagen because of its DNA intercalating nature.A catalyst composition for the feasible elimination of ethidium bromide using a broad spectrum of solar radiation was investigated.Nanostructured anatase TiO2 was synthesized by gel to crystalline conversion and its bandgap was engineered by doping with zirconium to effectively harness sunlight.The doped nanocrystals were characterized by X-ray diffraction,scanning electron microscopy,transmission electron microscopy,energy dispersive X-ray analysis,and UV-Vis spectroscopy.The formed crystals retained the anatase phase with a marginal increase in size.The pulverization process used to dope Zr into titania resulted in a nano and doped lattice with an increased and extended light absorption range,which gave a nearly five-fold increase in photoactivity over pure titania.The catalytic effect of the modified titania,the dopant concentration,and the dynamics of the dopant concentration on the charge carriers(trapping-recombination)for the degradation of the mutagen was investigated.The modified titania is capable of total ethidium bromide elimination in sunlight.The loss of its mutagenic property was confirmed by an Ames test.The induced revertant colonies observed were nil in the treated sample indicating a complete loss of the intercalating property of the mutagen. | S.SWETHA R.GEETHA BALAKRISHNA | 2011 | 催化学报2011，32，5： | 0 |
| 2 | Pd/Fe_(3)O_(4) supported on bio-waste derived cellulosic-carbon as a nanocatalyst for C-C coupling and electrocatalytic application显示文摘The current work describes the synthesis of a new bio-waste derived cellulosic-carbon supportedpalladium nanoparticles enriched magnetic nanocatalyst(Pd/Fe_(3)O_(4)@C)using a simple multi-step process under aerobic conditions.Under mild reaction conditions,the Pd/Fe_(3)O_(4)@C magnetic nanocatalyst demonstrated excellent catalytic activity in the Hiyama cross-coupling reaction for a variety of substrates.Also,the Pd/Fe_(3)O_(4)@C magnetic nanocatalyst exhibited excellent catalytic activity up to five recycles without significant catalytic activity loss in the Hiyama cross-coupling reaction.Also,we explored the use of Pd/Fe_(3)O_(4)@C magnetic nanocatalyst as an electrocatalyst for hydrogen evolution reaction.Interestingly,the Pd/Fe_(3)O_(4)@C magnetic nanocatalyst exhibited better electrochemical activity compared to bare carbon and magnetite(Fe_(3)O_(4)nanoparticles)with an overpotential of 293 mV at a current density of 10 mA·cm^(–2). | Vishal Kandathil Akshay Moolakkil Pranav Kulkarni Alaap Kumizhi Veetil Manjunatha Kempasiddaiah Sasidhar Balappa Somappa R.Geetha Balakrishna Siddappa A.Patil | 2022 | Frontiers of Chemical Science and Engineering2022，16，10： | 0 |
| 3 | A comprehensive review of pre-lithiation/sodiation additives for Li-ion and Na-ion batteries显示文摘Lithium/Sodium-ion batteries(LIB/SIB)have attracted enormous attention as a promising electrochemical energy storage system due to their high energy density and long cycle life.One of the major hurdles is the initial irreversible capacity loss during the first few cycles owing to forming the solid electrolyte interphase layer(SEI).This process consumes a profusion of lithium/sodium,which reduces the overall energy density and cycle life.Thus,a suitable approach to compensate for the irreversible capacity loss must be developed to improve the energy density and cycle life.Pre-lithiation/sodiation is a widely accepted process to compensate for the irreversible capacity loss during the initial cycles.Various strategies such as physical,chemical,and electrochemical pre-lithiation/sodiation have been explored;however,these approaches add an extra step to the current manufacturing process.Alternative to these strategies,pre-lithiation/sodiation additives have attracted enormous attention due to their easy adaptability and compatibility with the current battery manufacturing process.In this review,we consolidate recent developments and emphasize the importance of using pre-lithiation/sodiation additives(anode and cathode)to overcome the irreversible capacity loss during the initial cycles in lithium/sodium-ion batteries.This review also addresses the technical and scientific challenges of using pre-lithiation/sodiation additives and offers the insights to boost the energy density and cycle life with their possible commercial exploration.The most important prerequisites for designing effective pre-lithiation/sodiation additives have been explored and the future directions have been discussed. | Pranav Kulkarni Hyunyoung Jung Debasis Ghosh Mohammed Jalalah Mabkhoot Alsaiari Farid A.Harraz R.Geetha Balakrishna | 2023 | Journal of Energy Chemistry2023，，1： | 0 |
