Ananth Govind Rajan @ananthgr.bsky.social · 01/10/2026Our heartfelt thanks to Hindustan Petroleum Corporation Limited for funding this fundamental research project at the Department of Chemical Engineering, IISc, and we look forward to more such industry-academia partnerships. Will be happy to hear any feedback! 000
Ananth Govind Rajan @ananthgr.bsky.social · 01/10/2026It was a particularly rewarding collaboration with experimentalists Dr. Santhosh and Dr. Valavarasu at HPCL, and Dr. Amol Amrute at A*STAR. 101
Ananth Govind Rajan @ananthgr.bsky.social · 01/10/2026It is fulfilling that Anand is now a budding Assistant Professor at the Motilal Nehru National Institute of Technology (MNNIT), Allahabad, while Swastik, Srinibas, and Rahul are successful PhD students at the University of Rochester, IISc, and Cornell University, respectively. 100
Ananth Govind Rajan @ananthgr.bsky.social · 01/10/2026The project also involved former students Srinibas Nandi and Rahul Sheshanarayana, along with collaborators Santhosh Kotni and G Valavarasu from the Hindustan Petroleum Corporation Limited (HPCL), Amol Amrute from A*STAR Singapore, and Ambedkar Dukkipati from the Indian Institute of Science (IISc). 100
Ananth Govind Rajan @ananthgr.bsky.social · 01/10/2026Overall, the proposed methodology opens new directions for accurate modeling of catalytic reaction mechanisms. The research was mainly done by former C V Raman Postdoctoral Fellow Anand Mohan Verma, PhD student Shivam Chaturvedi, and former project associate Swastik Paul, who contributed equally. 100
Ananth Govind Rajan @ananthgr.bsky.social · 01/10/2026As part of this work, we also developed new algorithms, named automated reaction enumeration and elementary reaction identification, which enabled an exhaustive compilation of elementary reaction steps involved in CO2 hydrogenation. 100
Ananth Govind Rajan @ananthgr.bsky.social · 01/10/2026This is opposed to the splitting of a hydrogen molecule into two atoms, which then add to CO2 or other species on the catalyst surface. The new mechanism was verified by quantum-mechanical calculations and can lead to the discovery of efficient pathways for CO2 and CO hydrogenation in the future. 110
Ananth Govind Rajan @ananthgr.bsky.social · 01/10/2026What is noteworthy is that previous studies modeled only dozens, not even hundreds, of reactions. The proposed machine learning approach also revealed a new hydrogenation mechanism involving hydrogen atom donation. 110
Ananth Govind Rajan @ananthgr.bsky.social · 01/10/2026The results demonstrate that even large networks containing hundreds of reactions can predict products incorrectly, and only the proposed approach agrees with experimental trends for CO2 conversion and methanol production on copper. 100
Ananth Govind Rajan @ananthgr.bsky.social · 01/10/2026We developed a machine-learning-enhanced approach to enable kinetic modeling of massive reaction networks for CO2 hydrogenation, comprising about 10,000 elementary steps. 100
Ananth Govind Rajan @ananthgr.bsky.social · 01/10/2026Understanding the mechanisms underlying CO2 hydrogenation is challenging because it involves thousands of elementary steps occurring simultaneously on catalyst surfaces. 100

Ananth Govind Rajan @ananthgr.bsky.social · 06/09/2026The work was led by recently graduated PhD student Pradeep Dhondi, and involved former postdoc Sagar Ghorai. Many thanks to the Anusandhan National Research Foundation and the Infosys Foundation for funding the work, and to C-DAC for providing access to the Param Siddhi-AI supercomputer. 000
Ananth Govind Rajan @ananthgr.bsky.social · 06/09/2026We show that low edge charges sieve ions, but positive edge charges exclude boron, a difficult-to-remove contaminant. These design principles will enable the development of efficient, next-generation seawater desalination membranes for producing drinking water. 100
