“…It is estimated that biomass could provide about 25% of global energy requirements. 329,405,406 Agricultural crops, waste from food processing, litter from animal feedlots and many other sources of biomass can be converted into fuel gas, bio-alcohol, or biodiesel, or into a syngas from which chemicals and fuels can be synthesized. Biodiesel in particular has emerged as one of the best potential renewable energy sources to replace current petroleum-based transportation fuel.…”

“…Biodiesel in particular has emerged as one of the best potential renewable energy sources to replace current petroleum-based transportation fuel. 329 Although recent studies have proven the environmental and economical benefits of biodiesel production via heterogeneous catalysis, it remains challenging to develop suitable heterogeneous catalyst architectures that will facilitate the diffusion of viscous bio-oil feedstock during catalytic conversion. Most materials described to date exhibit micro and/or mesoporosity, which are not optimal for accommodating bulky triglyceride derivatives.…”

Nature evolved a variety of hierarchical structures that produce sophisticated functions. Inspired by these natural materials, colloidal self-assembly provides a convenient way to produce structures from simple building blocks with a variety of complex functions beyond those found in nature. In particular, colloid-based porous materials (CBPM) can be made from a wide variety of materials. The internal structure of CBPM also has several key attributes, namely porosity on a sub-micrometer length scale, interconnectivity of these pores, and a controllable degree of order. The combination of structure and composition allow CBPM to attain properties important for modern applications such as photonic inks, colorimetric sensors, self-cleaning surfaces, water purification systems, or batteries. This review summarizes recent developments in the field of CBPM, including principles for their design, fabrication, and applications, with a particular focus on structural features and materials' properties that enable these applications. We begin with a short introduction to the wide variety of patterns that can be generated by colloidal self-assembly and templating processes. We then discuss different applications of such structures, focusing on optics, wetting, sensing, catalysis, and electrodes. Different fields of applications require different properties, yet the modularity of the assembly process of CBPM provides a high degree of tunability and tailorability in composition and structure. We examine the significance of properties such as structure, composition, and degree of order on the materials' functions and use, as well as trends in and future directions for the development of CBPM.

“…The yield and quality of biodiesel can be highly affected by the surface area, surface acidity/basicity, and particle size of the catalysts used in the esterification and/or transesterification processes [22]. This has encouraged the development of novel recyclable solid acid nano-catalysts to replace conventional corrosive homogeneous acid catalysts [21,23], which can corrode reactors and requires further washing with neutralisation steps for their removal from the biodiesel and its by-products [24].…”

“…Modification of the surface of nanoparticles by integration of acidic functional groups (e.g. -SO 3 H) to produce solid acid catalysts for different applications has been highlighted in the literature over the recent years [8,11,21,24,[28][29][30][31][32][33][34][35][36][37][38]. This is because sulfonic acid functional groups on the surface of nanoparticles lead to the formation of porous materials with high accessibility to the active sites [39].…”

Highlights• A novel, efficient and recyclable mesoporous TiO 2 /PrSO 3 H solid acid nano-catalyst was synthesised.• We examined the catalytic activity, stability and reusability of synthesised mesoporous TiO 2 /PrSO 3 H.• The FAME yield from UCO was 98.3% under optimum process conditions.• Synthesised biodiesel from UCO satisfied ASTM D6751 and EN 14214 standards. ABSTRACTA novel, efficient and recyclable mesoporous TiO 2 /PrSO 3 H solid acid nano-catalyst was synthesised by the post-synthetic grafting of propyl sulfonic acid groups onto a mixed phase of a TiO 2 support. The synthesised nano-catalyst was characterised using FTIR, SEM, TEM, XPS, N 2 adsorption-desorption isotherms, XRD, DSC, TGA, and CHNS analysis. The percentage of loading for propyl sulfonic acid on the TiO 2 support was calculated using CHNS analysis and TGA. The catalytic performance of TiO 2 /PrSO 3 H on the production of the fatty acid methyl esters (FAME) via simultaneous esterification and transesterification reactions from used cooking oil (UCO) has been studied. The effects of different process parameters showed that 98.3% of FAME can be obtained after 9 hrs of reaction time with 1:15 molar ratio of oil to methanol, 60°C reaction temperature and 4.5 wt% catalyst loading. It was also found that the one-pot post-surface functionalisation strategy with hydrophilic functional groups (-SO 3 H) enhanced the acid strengths of the nano-catalyst providing more acid sites for the reactants, and improving the accessibility of methanol to the

A family of tungstated zirconia solid acid catalysts were synthesised via wet impregnation and subsequent thermochemical processing for the transformation of glucose to 5-hydroxymethylfurfural (HMF). Acid strength increased with tungsten loading and calcination temperature, associated with stabilisation of tetragonal zirconia. High tungsten dispersions of between 2 and 7 W atoms·nm −2 were obtained in all cases, equating to sub-monolayer coverages. Glucose isomerisation and subsequent dehydration via fructose to HMF increased with W loading and calcination temperature up to 600 °C, indicating that glucose conversion to fructose was favoured over weak Lewis acid and/or base sites associated with the zirconia support, while fructose dehydration and HMF formation was favoured over Brönsted acidic WOx clusters. Aqueous phase reforming of steam exploded rice straw hydrolysate and condensate was explored heterogeneously for the first time over OPEN ACCESSCatalysts 2014, 4 415 a 10 wt% WZ catalyst, resulting in excellent HMF yields as high as 15% under mild reaction conditions.
