Aluminium Fumarate MOF [Al(OH)(fum)]: Molecular Architecture & Performance Advantage
Aluminium Fumarate, structurally formulated as [Al(OH)(C4H2O4)]n (often commercially designated as Al-FUM or Basolite A520), represents a pinnacle in the domain of hydrothermally stable Metal-Organic Frameworks. Engineered from infinite corner-sharing AlO6 octahedra cross-linked by trans-fumarate linkers, this 3D microporous architecture establishes a highly robust 1D rhombic channel network. With a characteristic pore diameter of approximately 5.7 Å to 6.0 Å and an extraordinary Brunauer-Emmett-Teller (BET) specific surface area exceeding 1,100 m²/g, Aluminium Fumarate exhibits unprecedented thermodynamic stability and moisture-sorption kinetics.
Core Thermodynamic Advantage: Unlike conventional silica gels or zeolites requiring thermal regeneration temperatures above 150°C–200°C, Al-FUM exhibits an ideal S-shaped water vapor adsorption isotherm with a steep uptake step at low relative humidity (p/p₀ ≈ 0.25 to 0.30). Desorption occurs rapidly at temperatures as low as 65°C to 70°C, unlocking significant thermal efficiency when utilizing industrial waste heat or direct solar-thermal collectors.

Global Supply Performance Metrics
Empowering world-class industrial OEMs, research laboratories, and climate-tech innovators.
Global Commercialization & Supply Chain Dynamics of MOFs
The global transition from benchtop MOF synthesis to high-volume industrial utilization has historically been constrained by three structural bottlenecks: high organic solvent costs (e.g., DMF, DEF), non-continuous batch reactors, and thermal/hydrothermal degradation during long-term operations. Aluminium Fumarate has emerged as the premier candidate to solve these commercial hurdles.
1. Solvothermal vs. Green Hydrothermal Synthesis Economics
Traditional MOF production relies on toxic organic solvents that inflate production costs to over $1,000/kg, rendering commercial adoption non-viable. Our continuous green aqueous hydrothermal process synthesizes phase-pure Aluminium Fumarate in 100% water media using bio-derived fumaric acid and standard aluminium salts. This technical breakthrough dramatically lowers unit production costs, making enterprise-scale supply feasible for climate technology OEMs.
2. Form Factor Shaping: Granules, Pellets, and Coated Substrates
Raw MOF synthesis yields microcrystalline powders (<5 µm grain size), which incur catastrophic pressure drops when packed directly into gas fixed-beds or desiccant columns. As a premier exporter, our engineering service specializes in advanced binderless shaping technologies:
- Spheres & Extrudates: Engineered using sol-gel alumina or mesoporous silica binders (1.0 mm – 3.0 mm size), preserving over 90% of intrinsic BET surface area.
- Monolithic Washcoating: High-adhesion slurries for coating metal honeycombs, aluminum heat exchangers, and ceramic substrate wheels.
- Polymer Composite Membranes: Mixed-matrix membranes (MMM) blending Al-FUM into polyimide and PVDF matrices for targeted gas separation.
