Phosphorus nitride nano-dots as a versatile and metal-free support for efficient photoelectrochemical water oxidation

Phosphorous nitride dots induced efficient advanced oxidation with intrinsic chemiluminescence for organic pollutant degradation

In this work, we introduced new metal-free catalysts, phosphorus nitride dots (PNDs), into an environmentally friendly H2O2-SO32- system to generate abundant reactive oxygen species (O2˙-, ˙OH and SO4˙-) with strong intrinsic chemiluminescence (CL). The excellent catalytic ability of PNDs not only improved the degradation efficiency of organic pollutants, but also provided a promising prospect for deeply probing the mechanism of advanced oxidation processes (AOPs) by combining with CL.

Surface charge-directed borophene-phosphorous nitride nanodot heterojunction supports for enhanced photoelectrochemical performance

Complimentary surface-charged, nanosized 0D-0D hybrids of phosphorous nitride dots (PNDs) (ς = +9.5 mV) and borophene dots (BDs) (ς = -26.2 mV) having favourable band alignments are proposed for a type-II heterojunction. This hybrid model provides rapid carrier separation and carrier recombination resistance for enhanced PEC water oxidation.
