This review provides a recompilation of the most important and recent strategies employed to increase the efficiency of metal-organic framework(mOF)-based systems toward the photocatalytic hydrogen evolution(PHE)reaction through specific strategies:tailoring the photocatalytic activity of bare mOFs and guest@mOF composites,formation of heterojunctions based on mOFs and various photocatalysts,and inorganic photocatalysts derived from *** to the data reported in this mini-review,the most effective strategy to improve the PHE of mOFs relies on modifying the linkers with new secondary building units(SBUs).Although several reviews have investigated the photocatalytic activity of mOFs from a general point of view,many of these studies relate this activity to the physicochemical and catalytic properties of ***,they did not consider the interactions between the components of the photocatalytic *** study highlights the effects of strength of the supramolecular interactions on the photocatalytic performance of bare and mOF-based materials during PHE.A thorough review and comparison of the results established that metal-nanoparticle@mOF composites have weak van der Waals forces between components,whereas heterostructures only interact with mOFs at the surface of bare *** material derivatives from mOFs,we found that pyrolysis destroyed some beneficial properties of mOFs for ***,we conclude that adding SBUs to organic linkers is the most efficient strategy to perform the PHE because the SBUs added to the mOFs promote synergy between the two materials through strong coordination bonds.

Plant-based antimicrobial agents are readily available, cost-effective, and exhibit low toxicity, making them promising alternatives in combatting microbial infections. Among these plants, garlic (Allium sativum) stands out for its traditional medicinal use in effectively combating various microorganisms. In the poultry industry, preventing avian virus and bacterial infections is paramount for chicken husbandry. However, using conventional drugs poses potential risks to human health. Garlic, a widely used Asian plant in traditional medicine for various pathologies, has shown potential as an herbal prophylactic remedy against viral and bacterial infections. Recently, researchers explored garlic and its derivatives as a scientific strategy in veterinary practices for diverse purposes, such as improving poultry production characteristics and acting as antibiotic growth promoters. This comprehensive review delves into garlic and its derivatives as preventive and corrective treatments for viral diseases in laying hens and broilers. The paper highlights their potential effectiveness and safety as a natural means to enhance poultry health and welfare while mitigating the risks associated with conventional drug usage in the food industry.
