As one of the best sustainable approaches for visible-light production hydrogen (H2) to meet energy demands, semiconductor-based photocatalysis has received broad interest in recent decades. The fundamental restrictions graphitic carbon nitride (g-C3N4) as a promising metal-free photocatalytic semiconductor water splitting, like insufficient harvesting and high electron–hole (e/h) pairs recombination, have limited its applications this goal. In regard, optical, charge separation, surface features g-C3N4 can be tuned via engineering C/N vacancies, which is reviewed here splitting by g-C3N4. Reports confirm that enhanced resulting from vacancies are helpful adsorption on surface, improving water-splitting kinetics. First Review, improvements structural optical characteristics introducing especially nitrogen will discussed illustrate better performance. Then, various strategies creating controlling reviewed. critical roles optimizing performance also described, finally advances defective oxidation addressed.

Significant efforts have been dedicated to hydrogen production through photocatalytic water splitting (PWS) over the past five decades. However, achieving commercially viable solar-to-hydrogen conversion efficiency in PWS systems remains elusive. These face intrinsic and extrinsic challenges, such as inadequate light absorption, insufficient charge separation, limited redox active sites, low surface area, scalability issues practical designs. To address these issues, conventional strategies including heterojunction engineering, plasmonics, hybridization, lattice defects, sensitization, upconversion processes extensively employed. More recently, innovative hybrid like photonic crystal-assisted polarization field-assisted emerged, which improve absorption separation by harnessing slow photon effect, multiple scattering, piezoelectric, pyroelectric, ferroelectric properties of materials. This review article aims provide a comprehensive examination summary new synergistic approaches, integrating plasmonic effects, processes, crystal photocatalysis. It also explores role temperature suppressing exciton recombination during photothermic highlights emerging effects magnetic fields, periodic illumination, many-body large-hole polaron, anapole excitations, hold significant potential advance technology facilitate renewable generation.

Acetylene (C2H2), an industrially important gas, is produced by steam cracking of hydrocarbons and inevitably contains traces ethylene (C2H4) carbon dioxide (CO2) as impurities. Metal-organic frameworks (MOFs) further post-modified MOFs are versatile promising adsorbents for energy-efficient C2H2/C2H4 C2H2/CO2 separation selective adsorption C2H2 compared to energy-consuming conventional methods. Herein, Cu(I) ion generated structures from post-synthetic modification HKUST-1 chosen sites over both C2H4 CO2 gases. Protective ions were post-coordinative reduction Cu(II) nodes a using hydroquinone reducing agent create robust adsorptive sites. In the metal node reduced (HKUST-1-HQ), selectivity was enhanced not only but also presence site, virtue copper(I)-alkynyl chemistry. breakthrough test, did occur at coordinatively unsaturated site (HKUST-1), whereas capability appeared after monovalent copper introduced. Enhanced observed HKUST-1-HQ. The behavior (triple bond), (double (opposite quadruple moment) copper(II) open copper(I) originating same structure respectively studied understand gas sorption. HKUST-1-HQ, study four types possible Cu (Nodes II, III, IV, V) adsorbates revealed that Node IV preferential other three sites, CUS (bare HKUST-1). DFT computational simulation successfully demonstrated type plausible C2H2. Overall, HKUST-1-HQ exhibits greater moisture stability, improved selectivity, repeatability adsorbent.
