　　In this work, an efficient wide solar light-driven photocatalyst based on solar UV-blind SnO₂ nanospheres has been vanadium doped (V-doped SnO₂), and furthermore decorated with single atoms cobalt (SAs Co@V-doped SnO₂). In addition, for the next project the V-doped SnO₂ has been phosphate-modulated (PO4@V-doped SnO₂) and further has been modified with cobalt phthalocyanine (CoPc). Guided by density functional theory (DFT) calculations and experimental results, H-bond strengthened interfacial connection was established to purchase wide range of solar radiations and applied as an efficient photocatalysts for CO₂ conversion. The optimized products of 0.02%SAs Co@0.01%V-doped SnO₂ and 4CoPc/0.08%PO4-SnO₂ nanocomposites unveiled an unprecedented in the quantum efficiency, with narrow band gap and outstanding structural stability compare to the pristine solar UV-blind SnO₂. The much-extended photoactivities are accredited to the formation of strong H-bond between CoPc and PO4@V-doped SnO₂, that accelerated charge transformation as confirmed from Bader analysis and work functions, activation of O₂, and wide visible-light absorption, DFT and experimental results. We believe that these systems will also work for other metal phthalocyanines such as ZnPc, NiPc and HPc together with V-doped SnO₂, and deposition of single atoms such as Cu, Ni, and Zn together with V-doped SnO₂.

　　Habib Khan was born in Pakistan in December 1983, and now works at School of Physics, University of Electronic Science and Technology of China, as a post-doctoral researcher. He got his Ph.D. degree in Polymer chemistry from Nankai University in December 2018. After graduation he has done one postdoc at School of Chemical Engineering and Technology, Xi’an Jiaotong University in 2021. His expertise is focused on synthesis and photochemistry and electrochemistry of nanostructured materials. My current research interest is to develop efficient photocatalytic approaches to solar energy conversion (Water splitting/CO₂ conversion) and utilization by harvesting solar energy to produce molecular fuels and to degrade environmental pollutants. As a first and co-author, I have published over 20 professional papers in the international SCI journals, such as Macromolecules, “Adv Mater Interfaces”, “Polymer”, “Dalton transaction” “ACS Macro letter”, “J Colloid and Interface Sci”, “Polymer Chemistry”, and “Chemical Engineering Journal”. These papers have been positively cited for more than 600 times. World Journal.
