“…For composites with APIA, the diffraction peaks become much weaker, which is ascribed to the addition of amorphous aluminophosphate compounds. Interestingly, the additionally peaks around 2θ = 21.68° and 35.96° are observed in WBB burned off at 1000 °C, which are similar to the AlPO-17 crystals. , Therefore, it can be concluded that the residues not only consist of the amorphous carbon and aluminophosphate compounds but also contain AlPO-17 crystals, which would greatly improve the fire resistance of WBB …”

Aluminophosphate inorganic adhesive (APIA), as a binder for wood-based boards (WBB), is synthesized between Al(OH)3 and H3PO4 in solution with hydrothermal treatment in this study. Aluminophosphate compounds with hierarchical lamellar structure are observed on the fibers’ surface. The rheological behavior analysis reveals that the viscosity of APIA varied with its P/Al molar ratio [n(P)/n(Al)]. P–O–Al bridges are formed during the hydrothermal treatment of the APIA. The amounts of hydrogen bonds are formed between APIA and wood fibers, which could explain the improvement in mechanical properties of the WBB. In this study, the optimal n(P)/n(Al) in APIA is found to be 2.8, where the bonding strength, together with an acceptable viscosity are found at 1.83 MPa and 31.3 m Pa·s, respectively. Thermogravimetric analysis indicates that the residual weight of plywood is 44.97% greater than pure wood fibers, indicating the fire resistance of the WBB in the study is improved.

“…For Wood@AlP, it does not only present reduction in the peak intensity at 2θ = 15.60 and 22.97°but also exhibits additional peaks at around 21.9, 25.3, 27.2, 28.4, 29.7, 31.4, and 35.9°, which can be attributed to the crystal structure of the AlP compound (Figure S5). 41,42 Furthermore, the total weight loss of Wood@AlP (51.1%) is obviously lower than that of wood (86.2%), indicating that the AlP compound has been deposited on the wood surface (Figure S6).…”

Hierarchical Porous Aluminophosphate-Treated Wood for High-Efficiency Solar Steam Generation

Solar steam generation as a promising solar energy conversion technology has attracted considerable interest in achieving seawater desalination and water purification. Although wood with fast water transportation and excellent heat localization has drawn particular interest in regard to its application for solar steam generation, challenges still remain in terms of its complicated processing techniques and relatively low efficiency. Here, we propose a facile, cost-efficient, and scalable brushing method to prepare an aluminophosphate-treated wood (Wood@AlP) solar steam generation device. The aluminophosphate compound deposited on the wood surface can not only be considered as the Lewis acid catalyst capable of accelerating the formation of the carbon layer but also provide an aluminophosphate layer with a hierarchical porous structure, which is beneficial for broad solar absorption and vapor escape. On the other hand, benefiting from the natural hydrophilicity, low thermal conductivity, and excellent water transportation of wood, the obtained Wood@AlP device can float on seawater and exhibit a high solar thermal efficiency of 90.8% with a net evaporation rate of 1.423 kg m–2 h–1 under 1 sun illumination.

“…6.5. SAPO-17, the isostructural form of ERI-type zeolite, has also been primarily synthesized with low Si contents (Si/T<0.05) based on Lok et al gel composition (does not provide for synthesis of pure SAPO-17 with high Si/T without the aid of hydrofluoric acid (HF)) [62][63][64][65]. However, recent experimental and computational findings have identified newer OSDAs, gel compositions, and crystallization conditions that are more suitable for stabilizing the ERI-type framework than those utilized in the prior art.…”
