Abstract:
The whole world is facing two major burning problems of rapidly increasing pollution and upcoming shortage of energy resources. At this stage, advanced Oxidation Processes (AOPs) are emerging as green chemical pathways where photocatalysis is one of the promise process, It can provide oxidizing as well reducing environment simultaneously, which can solve both these issues. Hydrogen can be produced from photosplitting of water and it has been predicted as a fuel of future. Another existing challenge is global warming, where carbon dioxide has been considered to play a main role. It can also be reduced photocatalytically into useful fuels such as formic acid, formaldehyde, methanol, methane, etc. The major limitation of a photocatalyst is its little activity as it does not absorb in visible range as well as facile recombination of electron- hole pairs. Both these limitations can be controlled by increasing the photocatalytic activity of these semiconductors on modifying it using sensitization, composite formation, metal or non-metal doping, use of cocatalysts, Z-scheme, S- scheme, etc. This will be discussed in brief along with some other interesting applications of photocatalysis such as self-cleaning glasses, antifogging windscreen, antimicrobiological activity, etc.

Sukhadia University, Udaipur (2002-2005) & Head, Department of Polymer Science (2005-2008). He also served as Dean, P.G. Studies for a period of four years (2004-2008). He has served as Dean, Faculty of Science, PAHER University, Udaipur for six years (2011-2017). Presently, he is working as Professor of Eminence (Distinguished Professor of Chemistry) in Pacific University, Udaipur.
Prof. Ameta has occupied the coveted position of President, Indian Chemical Society, Kotkata (2000-2001) and is now lifelong Advisor (2002-continue). He was awarded a number of prizes during his career like National prize twice for writing Chemistry books in Hindi (1976 & 1978), Scientist of the Year Award (2002), Prof. M. N. Desai Award (2004), Prof. G. V. Bakore Award (2007), prof. W. U. Malik Award (2008), national Teacher Award (2011), and above all, Life Time Achievement Awards by Indian Chemical Society, Kolkata (2011), Indian Council of Chemists, Agra (2015), Association of Chemistry Teachers, Mumbai (2018), North Gujarat University, Patan (2022). He has successfully guided 110 students for Ph. D. Dr. Ameta has more than 450 research papers and 36 books to his credit. He has contributed Chapters in Books published by Trans-Tech, Switzerland: Nova Science, Taylor & Francis, and Apple Academic Press, USA. Three books on Green Chemistry, Microwave Assisted Organic Synthesis and Chemical Applications of Symmetry and Group Theory have been published by Apple Academic Press, USA. Two more books on Solar Energy Conversion & Storage and Photocatalysis; An Emerging Technology have been recently released by Taylor & Francis, USA and a book on Waste Water Treatments by AOPs by Elsevier. He has completed 5 Major Research Projects by DST, UGC, CSIR, and Ministry of Energy, Govt. of India. Prof. Ameta has delivered lectures and chaired sessions in National Conferences organized in almost every part of this country. He is also reviewer of number of international Journals. Prof. Ameta has an experience of more than 50 years of Teaching and Research.
Indian Chemical Society, Kolkata has published a Special issue of Journal of Indian Chemical Society in December 2008 to felicitate him on his 60th birthday and has instituted aa Award in his name as Prof. Suresh C. Ameta Award to be given to a senior chemist of repute from 2003 onwards. He has delivered Keynote Addresses in International Conferences at Tokyo, Japan in May 2022, Hangzhou, China in July 2022 and Kunming, China in 2023. Above all, he has pointed out some problems in h-index and proposed a complimentary index as Ameta or A-index for further improving h-index and for this, he received approval of copyright for this improvement.
