Heterostructured Photocatalyst Based Solar H2 Generation Process Using Abundant Elements
Subcategory (under Clean Energy): Hydrogen
Technology Readiness Level (TRL): TRL 4 - Early prototype
Technology Outline (Process Description)
The nitrogen deficient mesoporous carbon nitride (mpg-C3Nx) photocatalysts have been developed using the rational choice of uncommon precursor, and introduced porosity using Ludox as template, and nitrogen deficiency by heating under con- trolled atmosphere to drive solar to chemical fuel (H2 and CH4) generation. Further modification of mpg-C3Nx with Ni has been undertaken by microwave route and solvothermal to form atomically dispersed Ni decorated catalysts (mpg-C3NxNi) which exhibit drastic enhancement in the solar H2 generation activity. The robust photocatalyst- atomically dispersed Ni decorated mpg-C3NxNi exhibit drastically enhanced solar hydrogen at the rate from 200000 umolg-1h-1 to 1000000 umolg-1h-1 under sunlight by the atomically dispersed Ni modified catalyst mpg-C3NxNi, depending upon its synthesis route.
Salient Features/Advantages
- Process for the preparation of atomically dispersed Ni modified (2-D) nanostructured sheets-based catalyst mpg- C3NxNi by microwave assisted and solvothermal routes is one pot, involve low operational cost, fast (reaction duration 10 minutes) and less energy intensive
- The developed 2-D nanostructured sheets based heterostructured photocatalysts comprise of Earth abundant elements and thus are inexpensive
- The developed atomically dispersed Ni modified catalyst mpg-C3NxNi exhibit drastically enhanced solar hydrogen at the rate from 200000 umolg-1h-1 to 1000000 umolg-1h-1 under sunlight by the atomically dispersed Ni modified catalyst mpg-C3NxNi, depending upon its synthesis route
Key Outcomes
- A facile, less energy intensice and fast process for the preparation of atomically dispersed Ni modified (2-D) nanostructured sheets-based catalyst
- Developed photocatalysts comprise of Earth abundant elements and thus are inexpensive
- The atomically dispersed Ni modified catalyst mpg-C3Nx-Ni catalysts exhibit drastically improved hydrogen generation, that run the mini fan using the hydrogen fuel cell under direct sunlight
