Laser conversion of metal–organic frameworks (MOFs) has recently emerged as a fast and low-energy consumptive approach to create scalable MOF derivatives for catalysis, energy, and optics. However, due to the virtually unlimited MOF structures and tunable laser parameters, the results of their interaction are unpredictable and poorly controlled. Here, we experimentally base a general approach to create nano- to centimeter-scale MOF derivatives with the desired nonlinear optical and catalytic properties. Five three- and two-dimensional MOFs, differing in chemical composition, topology, and thermal resistance, have been selected as precursors. Tuning the laser parameters (i.e., pulse duration from fs to ns and repetition rate from kHz to MHz), we switch between ultrafast nonthermal destruction and thermal decomposition of MOFs. We have established that regardless of the chemical composition and MOF topology, the tuning of the laser parameters allows obtaining a series of structurally different derivatives, and the transition from femtosecond to nanosecond laser regimes ensures the scaling of the derivatives from nano- to centimeter scales. Herein, the thermal resistance of MOFs affects the structure and chemical composition of the resulting derivatives. Finally, we outline the “laser parameters versus MOF structure” space, in which one can create the desired and scalable platforms with nonlinear optical properties from photoluminescence to light control and enhanced catalytic activity.

“…There are fewer flaws in nanoparticles than in their bulk counterparts, and they have substantially better mechanical strength. However, some uses of nanomaterials may be negatively affected by their small size and high specific surface area, especially in applications for energy storage and conversion where nanomaterials have various benefits (Yan et al, 2022). The specific surface area, surface energy, and surface chemistry all play crucial roles in energy conversion and storage because these processes entail physical interaction and/or chemical reactions at the surface or interface.…”

In the past decade, high entropy alloys have been a research field of interest largely attributed to the enormous possibilities in alloy compositions, solid solution microstructures, and enhanced properties. The progress accomplished so far in the innovative growth and development of the mechanical, nanomechanical, chemical, electrochemical properties for energy storage systems using high entropy alloys on the nanoscale has limited reports in the literature. Mastering the synthesis of high entropy alloys is the deciding factor, if not the holy grail, when interested in a new material. For nanoparticles, in particular, this is true. Hence, the study on the production of high entropy alloy nanoparticles (HE-NPs) and the impact of synthesis on the structure of the resulting nanomaterial is valid for newly emerging components like HEA-NPs and the linkages between synthesis, structure, and property are essential for creating HEA-NP-based applications for energy storage applications, requiring the creation of a fundamental protocol to enable their mass manufacture and efficiency in service. In this study, we have presented a straightforward review of high entropy alloys, recent advances in high entropy nanoparticles and their various syntheses for energy and catalysis applications.

“…Subsequently, Deng et al revealed that the metal oxide clusters present in CPM-70 exhibited excellent compatibility with transition metals such as Mn 2+ , Fe 3+ , Co 2+ , Ni 2+ , Cu 2+ , and Zn 2+ . [93] Leveraging this compatibility, they successfully prepared a series of MTV-MOFs containing one, two, three, and five different metals. Through laser-induced synthesis, the MTV-MOFs were transformed into metal nanoparticles, including high entropy alloy nanoparticles.…”

Metal‐organic frameworks (MOFs) are crystalline materials with permanent pores constructed by self‐assembly of organic ligands and metal clusters through coordination bonds. Due to their diversity and tunability, MOFs have been used as precursors to be converted into other types of functional materials by pyrolytic recrystallization. Laser‐induced synthesis has been proven to be a powerful pyrolytic processing technique with fast and accurate laser irradiation, low loss, high efficiency, selectivity and programmability, which endow MOF derivatives with new features. Laser‐induced MOF derivatives exhibit high versatility in multidisciplinary research fields. In this review, we first briefly introduce the basic principles of laser smelting and the types of materials for laser preparation of MOF derivatives. Subsequently, we focus on the peculiarity of the engineering of structural defects and their applications in catalysis, environmental protection, and energy fields. Finally, we highlight the challenges and opportunities at the current stage with the aim of elucidating the future direction of the rapidly growing field of laser‐induced synthesis of MOF derivatives.This article is protected by copyright.
