<p>Anthropogenic climate and environmental changes increasingly threaten the sustainability of life on Earth, hindering sustainable development human societies. These detrimental ecological are driven by activities that have elevated atmospheric levels greenhouse gases toxic substances, increased inorganic organic pollutants in water bodies, led to accumulation solid waste soils. Over next two three decades, impacts change, pollution, soil contamination expected intensify, posing increasing risks health global stability. Considering these trends, it is essential implement robust mitigation adaptation strategies. This paper analyzes pollution problems from perspectives atmospheric, water, contamination. It summarizes current research heterogeneous catalysis for treating gaseous, liquid, phases, with an emphasis key challenges applying catalytic conversion technologies cost-effective industrial settings. Finally, strategies mitigating via discussed material flow, energy data flow. aims offer scientific insights enhance future practice remediation.</p>

Effects of the Hot-Drawing Process on the Pore Parameters, Gas Absorption and Mechanical Performances of Activated Carbon-Loaded Porous Poly(m-Phenylene Isophthalamide) Composite Fibres

Polymers, Journal Year: 2024, Volume and Issue: 16(24), P. 3452 - 3452

Poor breathability, inadequate flexibility, bulky wearability, and insufficient gas-adsorption capacity always limit the developments applications of conventional chemical protective clothing (CPC). To create a lightweight, breathable, flexible fabric with high gas-absorption capacity, activated carbon (AC)-loaded poly(m-phenylene isophthalamide) (PMIA) porous composite fibres were fabricated from mixed wet-spinning process integrated solvent-free phase separation process. By manipulating pore parameters as-spun fibres, exposure-immobilization AC particles on fibre surface can offer higher better AC-loading stability. improve mechanical properties AC-loaded further optimize pore-locking structures, impact hot-drawing evolution corresponding (including gas absorption performance, stability during loading) was clarified. After process, inhomogeneous morphologies composed mesopores/micropores changed into homogeneous decreased mesopores. With decrease in structural defects morphologies, tensile strength PMIA porous-drawn increased to 1.5 cN/dtex. Meanwhile, greater total volume specific area after hot drawing also maintained drawn at 98.53 mg/g. Furthermore, showed comparable performance commercial FFF02 layer terms static behaviour for different molecules absorption–desorption multi-cycling evaluations. In addition, due size reduction mesopores loading stretched more substantial.

Unveiling the Critical Role of Spatial Organization on Enzymatic Cascade Reactions in a Crystalline Framework with Hierarchical Porosity

ACS Materials Letters, Journal Year: 2024, Volume and Issue: unknown, P. 409 - 416

Published: Dec. 30, 2024

Enzymatic cascades are critical for energy conversion and chemical transformations in living organisms. Their ecofriendly nature high selectivity catalysis make them promising candidates improving cell-free systems. However, their applications have been limited by poor stability. Immobilized cascades, which can enhance activity, remain underexplored due to challenges such as ambiguous support structures difficulties controlling enzyme distribution. In this work, we employed NU-1510, a novel metal–organic framework (MOF) with crystalline hierarchical pore structure, stabilize an cascade that oxidizes ethanol acetaldehyde subsequently acetic acid. The impact of spatial organization on the kinetics was further investigated thanks structure MOF host. These findings pave way design advanced biocatalytic systems improved efficiency durability, potentially transforming sustainable manufacturing conversion.
