Photocatalysis is attracting increased attention in solving the energy crisis and environmental pollution. Graphitic carbon nitride (g-C3N4), a non-metal photocatalyst, has been regarded as an ideal photocatalyst to solve these problems because of its chemical stability unique optical properties. However, traditional g-C3N4 exhibits moderate photocatalytic activity due low specific surface area fast recombination rate photogenerated electrons. Among many modified materials, porous (PCN) can shortcomings PCN's number surface-active sites, area, light harvesting, diffusion adsorption/activation. frontier, comprehensive summary development PCN less reported. Thus, review on recent developments research urgently needed further promote advancement. In this review, synthesis methods, structures properties applications photocatalysts are described detail. The current challenges future PCN/PCN-based discussed. This may present up-to-date view provide in-depth understanding PCN-based photocatalysts.

The current environmental and potable water crisis requires technological advancement to tackle the issues caused by different organic pollutants. Herein, we report degradation of pollutants such as Congo Red acetophenone from aqueous media using visible light irradiation. To harvest solar energy for photocatalysis, fabricated a nanohybrid system composed bismuth ferrite nanoparticles with two-dimensional (2D) MXene sheets, namely, BiFeO3 (BFO)/Ti3C2 (MXene) nanohybrid, enhanced photocatalytic activity. hybrid BFO/MXene is simple low-cost double-solvent solvothermal method. SEM TEM images showed that BFO are attached onto surface 2D sheets. achieved found be 100% in 42 min dye (Congo Red) colorless pollutant (acetophenone) 150 min. exhibited large area 147 m2 g-1 measured via Brunauer-Emmett-Teller sorption-desorption technique, which largest among all derivatives. photoluminescence spectra indicate low electron-hole recombination rate. Fast efficient molecules two factors: larger lower rate, makes highly photocatalyst promising candidate many future applications.

The construction of intramolecular homojunction in the carbon nitride framework is one advantageous methods to improve photocatalytic performance. Based on molecular self-assembly strategy form homojunction, showed enhanced activity. However, disordered structure pristine g-C3N4 obtained using traditional approach inhibits dissociation and migration photocarriers. Here, we adopt a method prepare crystalline C3N4 (HCCN) with functional group modifications ternary by multistep thermal polymerization. band indicates that cyano cyanamide-based units HCCN samples have different highest occupied orbital/lowest unoccupied orbital energy levels, which constitute special through arrangement levels an internal electron field molecule. analysis photoelectron–hole pairs performance confirms accelerates interface charge transfer reduces reverse recombination. Moreover, compact greatly improves photogenerated charges. Femtosecond transient absorption spectra explain trajectory carrier kinetics confirm crystal semiconductor modified groups can promote excitons free This research provides idea obtain homojunctions.

Over the years, scarcity of fresh potable water has increased demand for clean water. Meanwhile, with advent nanotechnology, use nanomaterials photocatalytic degradation pollutants in wastewaters increased. Herein, a new type nanohybrids La- and Mn-codoped bismuth ferrite (BFO) nanoparticles embedded into transition-metal carbide sheets (MXene-Ti3C2) were prepared by low-cost double-solvent sol-gel method investigated their catalytic activity dark photoinduced conditions.
