Summary: It is reported a facile preparation of hierarchically porous g-C3N4 with uniform organic microstructure as a soft template. The in situ formed template in thiourea precursor solution effectively modifies the condensation of g-C3N4. The resulting g-C3N4 possesses hierarchical meso/macropores with higher surface area and pore volume, resulting in a 2.4-fold enhancement in photodegrading organic pollutant.

Summary: The synthesis of hierarchically porous Starbon(R) based materials from highly mesoporous Starbons(R) is reported. The hierarchically porous Starbons(R) show higher carbon dioxide adsorption capacities, better selectivity, and good stability under saturated water vapor conditions, compared to the mesoporous Starbon(R) precursors or conventional microporous activated carbon.

Summary: The researchers successfully engineered mesopores into microporous organic cages through host-guest interactions with long chain ionic surfactants, equipping the resulting hierarchically porous cage soft materials with charge-selective uptake and release abilities in solution. Interestingly, trapping enzymes within the cage turns it into a nanoreactor, leading to a 5-fold enhancement in enzymatic catalysis activity compared to free enzymes.

Summary: Incorporating metal nanoparticles (MNPs) with controlled size and spatial distributions into porous composites is challenging but beneficial for various applications. This study presents a method to immobilize highly dispersed MNPs (Pd, Ir, Pt, Rh, and Ru) with controlled size (<2 nm) on hierarchically micro-and mesoporous organic cage supports. The functional heads on the ionic surfactants and nanoconfinement of pores guide the nucleation and growth of MNPs, resulting in a uniform distribution and prevention of agglomeration.

Summary: This study utilizes in situ 2D hard X-ray ptychography (XRP) and 3D ptychographic X-ray computed tomography (PXCT) to investigate the synthesis process of hierarchically porous materials. The XRP allows for the monitoring of textural changes, while PXCT provides quantitative information on pore structures. The findings are corroborated with traditional pore characterization methods, leading to a better understanding of the synthesis pathways of porous materials.
