“…This decrease in size and agglomeration could be attributed to calcination of dopamine wrapped BM-ZIF that leads to the breakage of the organic framework along with a dopamine coating layer and in accordance with the reported literature. 28,29 The homogeneous formation of CA-PANI electrospun nanofibers at the surface of the three-dimensional microporous skeleton NF is shown in Figures 1C and S1A. The sizes of one-dimensional CA-PANI electrospun nanofibers were in the range of 79 nm.…”

Developing a clean and efficient noble metal free electrocatalyst for oxygen evolution reaction (OER) is urgently needed to accelerate water splitting green energy conversion systems. Herein, we reported the fabrication of a noble metal-free electrocatalyst based on Zn and Co loaded porous C decorated cellulose acetate-polyaniline (ZnCo-C/CA-PANI) electrospun nanofibers at the surface of nickel foam (NF). The smooth coating of CA-PANI electrospun nanofibers at the surface of NF helps in exposing the maximum fraction of ZnCo-C based electrocatalyst and uniform flow of ions at the entire surface, thus resulting in high OH − adsorption capability. The designed ZnCo-C/CA-PANI@NF electrode acts as an efficient electrocatalyst for oxygen evolution reaction (OER) in an alkaline medium and offers a lower onset potential (1.34 V vs RHE), a small Tafel slope of 42 mV/dec, and high stability. These results suggest a concept of exploring more such noble metal free hybrid materials that could induce the efficient electrocatalytic water splitting for sustainable energy conversion.

The accumulation of carbon dioxide (CO2) pollutants in the atmosphere begets global warming, forcing us to face tangible catastrophes worldwide. Environmental affability, affordability, and efficient CO2 metamorphotic capacity are critical factors for photocatalysts; metal-organic frameworks (MOFs) are one of the best candidates. MOFs, as hybrid organic ligand and inorganic nodal metal with tailorable morphological texture and adaptable electronic structure, are contemporary artificial photocatalysts. The semiconducting nature and porous topology of MOFs, respectively, assists with photogenerated multi-exciton injection and adsorption of substrate proximate to void cavities, thereby converting CO2. The vitality of the employment of MOFs in CO2 photolytic reaction has emerged from the fact that they are not only an inherently eco-friendly weapon for pollutant extermination, but also a potential tool for alleviating foreseeable fuel crises. The excellent synergistic interaction between the central metal and organic linker allows decisive implementation for the design, integration, and application of the catalytic bundle. In this review, we presented recent MOF headway focusing on reports of the last three years, exhaustively categorized based on central metal-type, and novel discussion, from material preparation to photocatalytic, simulated performance recordings of respective as-synthesized materials. The selective CO2 reduction capacities into syngas or formate of standalone or composite MOFs with definite photocatalytic reaction conditions was considered and compared.

Photocatalytic CO2 reduction by solar energy into carbonaceous feedstock chemicals is recognized as one of the effective ways to mitigate both the energy crisis and greenhouse effect, which fundamentally relies on the development of advanced photocatalysts. Here, the exploration of porous microrod photocatalysts based on novel NiCoO solid solutions derived from bimetallic metal–organic frameworks (MOFs) is reported. They exhibit overall enhanced photocatalytic performance with both high activity and remarkable selectivity for reducing CO2 into CO under visible‐light irradiation, which are superior to most related photocatalysts reported. Accordingly, the Ni0.2‐Co0.8‐O microrod (MR‐N0.2C0.8O) photocatalyst delivers high efficiency for photocatalytic CO2 reduction into CO at a rate up to ≈277 µmol g–1 h–1, which is ≈35 times to that of its NiO counterpart. Furthermore, they display a high selectivity of ≈85.12%, which is not only better than that of synthesized Co3O4 (61.25%) but also superior to that of reported Co3O4‐based photocatalysts. It is confirmed that the Co and Ni species are responsible for CO2CO conversion activity and selectivity, respectively. In addition, it is verified, by adjusting the Ni contents, that the band structure of NiCoO microrods can be tailored with favorable reduction band potentials, which thus enhance the selectivity toward CO2 photoreduction.
