The adjustment of pore sizes and environments of APMOFs can be finely tuned through judicious combination of organic ligands, anion pillars, and metal ions. Compared to widely investigated anion pillars, organic ligands are more crucial as they allow for a broader range of pore sizes and environments at the nanometer scale. Furthermore, different from the bidentate ligand-based APMOFs that typically form three-dimensional (3D) frameworks with <i><b>pcu</b></i> topology, APMOFs constructed using multidentate nitrogen(N)-containing ligands (with a coordination number ≥ 3) offer opportunities to create APMOFs with diverse topologies. The larger dimensions and possible distortion of multidentate N-containing ligands prove advantageous for addressing multi-component hydrocarbon separations encompassing a broad spectrum of dynamic diameters. Therefore, this Review summarizes the structural characteristics of multidentate ligand-based APMOFs and their enhanced performances for gas separation and purification processes. Additionally, it discusses current challenges and prospects associated with constructing multidentate ligand-based APMOFs while providing prospects.

As a sustainable green energy source, solar energy provides energy for human production and life. In recent years, the reported single-atom catalysts (SACs) have higher atom utilization and better catalytic efficiency than traditional heterogeneous catalysts. In the field of photocatalysis and photothermal synergistic catalysis of CO₂ conversion, single-atom catalysts can reduce the reaction temperature and pressure, improve the catalytic activity, and improve the selectivity of the reaction. In this mini-review, the basic mechanism and classification of CO₂ reduction are introduced, and then the roles and differences of single-atom catalysts in photocatalysis and photothermal catalysis are introduced. In addition, according to the reduction product types, the recent research progress of single-atom catalysts in photoconversion and photothermal CO₂ conversion was reviewed. Finally, the challenges of monoatomic photocatalytic and photothermal CO₂ reduction technologies have prospected. This mini-review hopes to provide an in-depth understanding of the roles of single atoms in photocatalysis and photothermal catalysis and to shed light on the actual production and application of renewable energy.

Herein, we treat the UV crosslinked SMP as a thermoviscoelastic solid and derive analytical solutions to predict the maximum recovery stress under fully constrained shape recovery and shape recovery ratio under partially constrained shape recovery. Effects of training parameters including programming strain, programming temperature, fixing temperature, storage time, recovery temperature and constraining stress have been investigated through parametric studies. Good agreement has been achieved among theoretical prediction, experimental investigation and numerical simulation.

Nonetheless, the utilization of solar energy for water evaporation encounters challenges, primarily manifested in low evaporation rates and efficiency. Herein, we introduced an approach involving the development of a biomass-based hybrid engineering hydrogel evaporator, denoted as CLC (chitosan and lignosulfonate sodium hybrid hydrogel with a carbon nanotube). The construction of this evaporator involves the straightforward blending of lignosulfonate sodium (LS) and marine polysaccharide biomass chitosan (CS) with carbon nanotubes (CNT) serving as the photothermal materials. The interaction between the sulfonic group of LS and the amino group of CS with water molecules, facilitated by hydrogen bonding and electrostatic interactions, reduces the evaporation enthalpy of water, thereby lowering the energy demand for evaporation. Furthermore, the incorporation of LS reduces the thermal conductivity of the as-prepared hydrogel and promotes photothermal management to mitigate heat loss. The CLC hydrogel demonstrates an evaporation rate of 2.48 kg m^–2 h^–1 and energy efficiency of 90% under one sun illumination. Moreover, the CLC hydrogel exhibits excellent antibacterial properties (98.4%), ensuring that desalinated water meets drinking standards.
