“…The UV−vis absorbance spectra (Figure 2D) showed that ZIF-67 exhibit high absorbance values compared to the ZIF-8, resulting in high light-harvesting capability and enhanced catalytic activities. 35 The FS spectra (Figure 2E) and PL spectra (Figure 2F) reveal that ZIF-67 has enhanced charge separation compared to ZIF-8. 36,37 The specific surface area (Figure 2G) and pore diameter distribution (Figure 2G inset) results indicated that ZIF-67 has a larger surface area (i.e., 1630.6 m 2 g −1 ) and pore diameter (25 nm) compared to the ZIF-8 (i.e., 1370.3 m 2 g −1 and 20 nm).…”

The continuous rise in atmospheric CO 2 concentration, overconsumption of energy resources, and release of extraordinary organic pollutants are challenging issues of the modern era. Catalytic technology offers a promising solution to tackle these energy and environmental challenges in parallel by facilitating highly effective and sustainable processes. Herein, we report the fabrication of a series of different nature polyarylimide (PAI)-based covalent−organic frameworks (COFs) via the polycondensation reaction by altering linkers, organic solvents, and other experimental conditions. To optimize their catalytic performance, the resultant PAI-COFs were further decorated with metal−organic frameworks (ZIF-67). The decoration of COF4 with ZIF-67 led to adjusted bandgaps, created an active site, enhanced charge separation and migration of photoexcited electron−hole (e−h) pairs, extended the light absorption to the visible region, and also facilitated the transferring of electrons between the COFs and MOFs via the photoelectron modulation approach. Based on our findings, it is confirmed that COF4 and ZIF-67 (MOFs) are the optimal catalysts compared to the other COFs (COF1, COF2, and COF3) and MOFs (ZIF-8). Interestingly, compared to the pristine COF4, the 5ZIF-67/COF4 nanohybrid revealed ∼8-fold and ∼5.3-fold for CO 2 conversion, direct CO 2 capturing, and photoelectrochemical CO 2 conversion with a faradaic efficiency of 50%. Likewise, the as-fabricated catalyst also exhibits exceptional activities for photocatalytic hydrogen production and pollutant oxidation. Ultimately, this work will provide a roadmap for the design and fabrication of COF-based nanohybrids for energy and environmental applications.

Modern research has made the search for high-performance, sustainable, and efficient energy storage technologies a main focus, especially in light of the growing environmental and energy-demanding issues. This review paper focuses on the pivotal role of biomass-derived carbon (BDC) materials in the development of high-performance metal-ion hybrid supercapacitors (MIHSCs), specifically targeting sodium (Na)-, potassium (K)-, aluminium (Al)-, and zinc (Zn)-ion-based systems. Due to their widespread availability, renewable nature, and exceptional physicochemical properties, BDC materials are ideal for supercapacitor electrodes, which perfectly balance environmental sustainability and technological advancement. This paper delves into the synthesis, functionalization, and structural engineering of advanced biomass-based carbon materials, highlighting the strategies to enhance their electrochemical performance. It elaborates on the unique characteristics of these carbons, such as high specific surface area, tuneable porosity, and heteroatom doping, which are pivotal in achieving superior capacitance, energy density, and cycling stability in Na-, K-, Al-, and Zn-ion hybrid supercapacitors. Furthermore, the compatibility of BDCs with metal-ion electrolytes and their role in facilitating ion transport and charge storage mechanisms are critically analysed. Novelty arises from a comprehensive comparison of these carbon materials across metal-ion systems, unveiling the synergistic effects of BDCs’ structural attributes on the performance of each supercapacitor type. This review also casts light on the current challenges, such as scalability, cost-effectiveness, and performance consistency, offering insightful perspectives for future research. This review underscores the transformative potential of BDC materials in MIHSCs and paves the way for next-generation energy storage technologies that are both high-performing and ecologically friendly. It calls for continued innovation and interdisciplinary collaboration to explore these sustainable materials, thereby contributing to advancing green energy technologies.

Perovskites are bringing revolutionization in a various fields due to their exceptional properties and crystalline structure. Most specifically, halide perovskites (HPs), lead-free halide perovskites (LFHPs), and halide perovskite quantum dots (HPs QDs) are becoming hotspots due to their unique optoelectronic properties, low cost, and simple processing. HPs QDs, in particular, have excellent photovoltaic and optoelectronic applications because of their tunable emission, high photoluminescence quantum yield (PLQY), effective charge separation, and low cost. However, practical applications of the HPs QDs family have some limitations such as degradation, instability, and deep trap states within the bandgap, structural inflexibility, scalability, inconsistent reproducibility, and environmental concerns, which can be covered by encapsulating HPs QDs into porous materials like metal−organic frameworks (MOFs) or covalent−organic frameworks (COFs) that offer protection, prevention of aggregation, tunable optical properties, flexibility in structure, enhanced biocompatibility, improved stability under harsh conditions, consistency in production quality, and efficient charge separation. These advantages of MOFs-COFs help HPs QDs harness their full potential for various applications. This review mainly consists of three parts. The first portion discusses the perovskites, halide perovskites, lead-free perovskites, and halide perovskite quantum dots. In the second portion, we explore MOFs and COFs. In the third portion, particular emphasis is given to a thorough evaluation of the development of HPs QDs@MOFs-COFs based materials for comprehensive investigations for next-generation materials intended for diverse technological applications, such as CO 2 conversion, pollutant degradation, hydrogen generation, batteries, gas sensing, and solar cells. Finally, this review will open a new gateway for the synthesis of perovskite-based quantum dots.
