Hexagonal boron nitride with functional groups for efficient photocatalytic reduction of nitrate without additional hole scavengers

Reaction mechanism and selectivity regulation of photocatalytic nitrate reduction for wastewater purification: progress and challenges

“…80 Some previous studies have designed photocatalysts to achieve high nitrate removal and nitrogen selectivity. 41,84 For example, the surface-functionalized hexagonal boron nitride (h-BN) 85 was applied to the photocatalytic nitrate reduction under UV light (l z 365 nm) without a sacricial electron donor which realizes high nitrate removal of 97.94% and high nitrogen selectivity of 97.31% (Fig. 5a and b).…”

Unraveling Rigidified Superexchange Couplings in Organic Donor–Acceptor Polymers for Boosting the Photocatalytic Reduction of Nitrate

“…5−7 As an alternative, photocatalytic nitrogen reduction to generate NH 3 (PNN) represents a sustainable development method because this process converts waste chemicals into valuable resources. 8,9 Nevertheless, photocatalytic activity is often restricted by the strongly binding and kinetically inert nitrate species as well as the multielectron and multiphoton process of PNN. 10,11 Therefore, the progress toward high-efficiency PNN is urgent but still challenging.…”

“…Nitrate contamination, mainly derived from the abuse of fertilizers, emission of atmospheric nitrogen oxides, and abandonment of industrial sewage, has attracted much attention due to its negative impact on the environment and human health. − To reduce this serious contamination, several strategies including catalytic denitrification, reverse osmosis, ion exchange, adsorption, and chemical denitrification have been proposed. − As an alternative, photocatalytic nitrogen reduction to generate NH 3 (PNN) represents a sustainable development method because this process converts waste chemicals into valuable resources. , Nevertheless, photocatalytic activity is often restricted by the strongly binding and kinetically inert nitrate species as well as the multielectron and multiphoton process of PNN. , Therefore, the progress toward high-efficiency PNN is urgent but still challenging.…”

Controllable Synthesis, Photocatalytic Property, and Mechanism of a Novel POM-Based Direct Z-Scheme Nano-Heterojunction α-Fe2O3/P2Mo18

“…Researchers are committed to exploring the usage of clean energy in the face of environmental concerns. Photocatalysis technology has been widely used in many fields in recent years, including in photocatalytic hydrogen production [ 1 ], photocatalytic carbon dioxide production of organic matter [ 2 ], photocatalytic degradation of nitrate [ 3 ], photocatalytic synthesis of ammonia [ 4 ], and pollutant degradation [ 5 ]. One of the most efficient approaches to tackling environmental problems is to employ photocatalysts to degrade organic contaminants in water using sunlight [ 6 , 7 , 8 ].…”
