In this work 𝗥𝘂𝗽𝗮𝗸 highlights that through appropriate choice of donor-acceptor moieties one can introduce anisotropic charge distribution into a conjugated microporous polymers (CMPs). This tailored electronic structure of CMPs can enhance charge separation; reduce exciton binding energy and supress charge recombination. Carrying forward our past initiatives to reduce CO2, this acetylene-linked CMP serve as an effective photocatalyst to reduce CO2 to methanol with 90% selectivity, offering a sustainable path toward clean fuel through solar driven CO2 utilization.

The term “𝗙𝗲-𝘀𝗼𝗰-𝗠𝗢𝗙” specifically refers to a variant of Metal-Organic Framework (M*F) constructed using Fe3O metal nodes arranged in a soc (square-octahedron) topology and assembled with ABTC linker. Traditional soc-M*F synthesis requires modulators for crystallinity and phase control. In this work, 𝗕𝗵𝗮𝗯𝗮𝗻𝗶 and 𝗦𝘂𝗱𝗶𝗽 came up with a modulator-free synthetic strategy to synthesize Fe-soc-C M*F with high crystallinity and porosity. This M*F demonstrated excellent efficiency towards aerobic organic photocatalysis, including oxidative coupling of benzylamine and synthesis of benzimidazoles.

Are you interested in sustainable CO₂ reduction strategies using biomass-derived hydrogen donors instead of molecular hydrogen? Then don’t miss our latest work published in 𝗔𝗱𝘃𝗮𝗻𝗰𝗲𝗱 𝗙𝘂𝗻𝗰𝘁𝗶𝗼𝗻𝗮𝗹 𝗠𝗮𝘁𝗲𝗿𝗶𝗮𝗹𝘀 by 𝗦𝘂𝗱𝗶𝗽!

In collaboration with 𝗥𝗲𝗹𝗶𝗮𝗻𝗰𝗲 𝗜𝗻𝗱𝘂𝘀𝘁𝗿𝗶𝗲𝘀 𝗟𝗶𝗺𝗶𝘁𝗲𝗱, we've developed a catalytic process that simultaneously converts CO₂ and glycerol (two abundant and under-utilized feedstocks) into formic acid and lactic acid, using a NiO/ZrO₂ catalyst. This process not only adds value to waste streams but also offers a green route to high-demand chemicals. Importantly, our partners at RIL have conducted a detailed techno-economic evaluation to assess its real-world viability and commercialization potential.

Dr. 𝗦𝘂𝗱𝗶𝗽 𝗕𝗵𝗮𝘁𝘁𝗮𝗰𝗵𝗮𝗿𝗷𝗲𝗲 successfully defended his PhD thesis titled "CO2 as C1 feedstock for the synthesis of valuable chemicals using porous nanomaterials as heterogeneous catalyst"

Congratulations and Best wishes for your future endeavors!

From industrial perspective, Brønsted acid catalysts are essential for various organic transformation reactions. Compared to homogeneous acid catalysts, heterogeneous counterparts offer ease of separation and reusability. Organic based, metal-free, crystalline Brønsted acid heterocatalysts are rare and difficult to synthesize. Covalent organic frameworks (COFs) with high specific surface area, stability and desired organic functionality, have huge potential as heterogeneous organocatalysts. In this regard, 𝗦𝘂𝗱𝗶𝗽 and 𝗦𝗮𝗻𝘁𝘂 came up with a -SO3H group attached COF (TFR-TDS-COF). The crystallinity along with high NH3 uptake capacity (acidity) of the material, facilitated various acid-catalyzed organic reactions like amination of epoxides, cycloaddition and acetalization reactions, with excellent conversion and selectivity.

What happens when we pyrolyze a metal-organic framework?
We get a carbon matrix containing metal nanoparticles. But what happens when we pyrolyze a M*F containing binary ligands with different decomposition temperature? In this study, 𝗦𝗮𝘆𝗮𝗻𝘁𝗮𝗻 and 𝗥𝘂𝗽𝗮𝗸 unveiled the morphological evolution of a mixed-ligand Ni-M*F during pyrolysis.
Thanks to its unique morphology that invokes high specific surface area and surface roughness, which facilities the electroreduction of CO2 to methanol.
Nice collaboration with 𝗣𝗿𝗼𝗳. 𝗧𝗵𝗮𝗽𝗮, SRM University for the theoretical insights.

5-Aminosalicylic acid (5-ASA), a well-known drug have the ability to bind strongly with metals like titanium. This work highlights a new organic-inorganic hybrid titanium phosphate (H-TiPOx) containing 5-ASA inside it's framework. We found that unlike other derivatives of salicylic acid, this molecule imparts high Brønsted acidity to the material. Therefore, we have used this H-TiPOx as a solid acid catalyst for acetalization of glycerol, an industrial waste to selectively (99%) produce solketal, a fuel additive.

If you are interested in porous organic semiconductor-based catalysts, please check out our recent article in 𝗦𝗺𝗮𝗹𝗹 by 𝗦𝘂𝗱𝗶𝗽 and 𝗦𝘂𝗺𝗮𝗻𝘁𝗮. In this article, we came up with a new donor-acceptor based conjugated microporous polymer with high BET surface area of 1575 m2g-1 and nanoscale porosity of 1.7 nm, where the carbazole unit acts as a donor center and the biphenyl moieties serve as acceptor centers, and both of these properties account for lowering the band gap of this material. Under the illumination of light, these donor-acceptor centers generate free electron species which can easily convert triplet oxygen to singlet oxygen. Utilizing this property, this material was used as a photocatalyst for various organic transformation reactions, like oxidative benzylamine coupling and benzimidazole synthesis.
