Researchers at CSIR-Nationwide Bodily Laboratory and IIT Madras have fabricated MoS2-coated GaN nanorods on tungsten foil to enhance the photoelectrochemical effectivity of water splitting. Gallium nitride nanorods, valued for electron mobility and stability, face limitations from their extensive bandgap limiting photo voltaic absorption. To handle this, the staff built-in molybdenum disulfide – a catalytic materials – onto the nanorods.
MoS2/GaN nanorods demonstrated a photocurrent density of about 172 microamperes per sq. centimeter, outperforming naked GaN nanorods by an element of two.5. This enchancment was linked to Kind II band alignment, which reinforces cost separation, decreases cost switch resistance, and will increase lively websites.
The heterostructures have been developed utilizing atmospheric stress chemical vapor deposition and laser molecular beam epitaxy. Supplies evaluation utilizing Raman spectroscopy, X-ray diffraction, and X-ray photoelectron spectroscopy confirmed hexagonal phases and mapped digital states.
These findings counsel that MoS2 integration with GaN nanorods offers a pathway to advance solar-driven hydrogen manufacturing know-how. The mission obtained assist from CSIR-FIRST and SAMMARTH. Future work will concentrate on scaling the strategy for industrial utility.
