A highly defined multi-layered 2D sulphur nanosheets have been prepared from 0D dots by hydrothermal based growth process. Slow transformation of to sheets allow reorganization elemental and containing functional groups, resulting higher crystallinity in with respect dots. It is further correlated the detailed photophysical studies. Low temperature photoluminescence spectra confirm that exciton binding energy are lower than The exciton-phonon coupling also sheet Overall, photoinduced charge separation process improves throughout matrix sheets. supported electrochemical impedance spectroscopy transient photocurrent Finally, both used for photocatalytic azo bond formation where electrons holes utilized simultaneously. Results suggest almost 3 folds enhancement catalytic efficiency without any metal co-catalyst. Controlled experiments happens through complete photocatalysis Detailed mechanism has proved identifying intermediates free radicals photo-responsive EPR studies various chemical scavenging experiments.
