“…This may be due to the coordination complexation reaction between As(III) and M-O on the laminate material, which produced a number of complexes. 51 The 1386 cm À1 peak representing Mn-O shied to 1397 cm À1 , further conrming that Mn-O participated in the reaction. Combined with the adsorption reaction model and XRD analysis, As(III) was partially oxidised to As(V), forming As-O or As-O-As.…”

“…As it is clear, all the patterns exhibit a broad band at about 3403 cm −1 , corresponding to the stretching vibration of H 2 O molecules 6,38 . Generally, the peaks at the lower wavenumber (below 1000 cm −1 ) represent oxygen‐metal stretching and bending vibration bonds 39 . Moreover, the ligand's (H 2 BDC) out of plane C − H bending vibration in the benzene ring can be observed at 752 cm −1 .…”

Summary Metal oxide/organic framework modification through mixing different metal ions is one of the most ingenious methods in material science. This study investigates elaborately designed bimetallic Fe/Mn, tri‐metallic NiFe/Mn‐metal organic frameworks, and their derived metal oxide nanocomposites for supercapacitor application. The novel bi‐ and tri‐metallic MOFs have shown substantially different morphologies consisting of hexagonal bipyramid and interconnected sheets respectively. After calcination, the materials have altered to spinel FeMn2O4 and Ni0.5Fe0.5Mn2O4 with porous nanorods and hierarchical texture features respectively. The diverse morphologies with considerably large surface areas of the mixed metallic MOFs and the derived oxides make them efficient electrochemical electrodes. Ni incorporation also enhances the capacitive behavior of the electrodes and NiFe/Mn‐MOF exhibits a superior specific capacitance of 1640 F g−1 at 1 A g−1. Furthermore, the FeMn2O4 and Ni0.5Fe0.5Mn2O4 nanostructures reveal highly stable capacitance with retention of 93 and 94% over 5000 cycles respectively. Besides, the assembled NiFe/Mn‐MOF//AC asymmetric supercapacitor represents significant energy and power densities of 75 Wh kg−1 and 1166 W kg−1 at 1.5 A g−1 respectively. It also has relatively high stability with capacitance retention of 73% over 5000 cycles.

Coal gangue (CG), which is mainly generated during coal excavation, mining, and coal washing, is an industrial solid waste that is recognized as an environmental pollutant. The ever‐increasing amount of CG produced is a serious threat to the ecological environment and property safety, especially in China, which is the largest coal producer and consumer in the world. Considerable studies have investigated means for utilizing CG worldwide. This review summarizes and discusses various porous inorganic materials made from CG, including cement‐based porous materials, porous bricks, porous ceramics (cordierite and mullite) and glasses, porous geopolymers, zeolites, aerogels, and porous carbon materials. Different preparation processes and performances of each type of porous inorganic materials were reviewed. Porous CG‐based materials can be used as promising adsorbents for the removal of various pollutants and have good potential for use in construction industry as well as catalyst material applications. Besides, porous materials obtained from CG have also been tested as slow‐release fertilizers after the absorption of phosphate, as electrode materials, and as oil‐in‐water separation agents. The systematic summary of porous materials based on CG aims at promoting high‐value‐added applications for this waste. Future research directions for the use of CG as a raw material are also presented.
