“…For example, ordered CBPM, widely referred to in the literature as three-dimensionally ordered macroporous materials (3DOM) or inverse opals, are of particular interest in photocatalysis due to their photonic properties as well as their superior mass transfer through interconnected pore channels. 67,330 This section will focus on the application of CBPM to distinct catalytic reactions, with emphasis on the advantages of CBPM structural parameters for catalyst systems, namely the ability to control the composition, porosity, and periodicity of the structure. Table 1 lists specific examples of colloid-based porous catalysts that have been fabricated and studied, focusing on the past four years.…”

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.

“…In this context, nanophotocatalytic materials emerge as being among the most promising solutions for photonic-energy storage in the form of H 2 . As we discuss herein, the same photophysical machinery can be used to catalyze the degradation/transformation of environmental pollutants such as toxic organics of high-valency metals (Dong S. et al, 2015;Fagan R. et al, 2016).…”

Environmental remediation and energy production are currently listed among the priority tasks by administration bodies, stakeholders and market competition. In this context, nanomaterials present competitive advantages in terms of performance and production costs. In the present critical review, the current state of the art of nanomaterials used in environmentally benign technologies exploiting solar irradiation such as H 2 production, water-splitting and photocatalysis are discussed. Factors determining the overall efficiency are articulated in a single "photophysical efficiency" equation. The physical meaning, limits and constraints of each factor are analyzed, updated and examples are discussed. The article highlights the main structure-function relationships in tandem with the limitations posed by the particle's physicochemical properties, production method, and the prerequisites posed by regulatory bodies and market needs. Several misconceptions are highlighted with regard to performance and yields that ultimately impact the end use of the nanomaterials. Current targets/limitations posed by the US Department of Energy are discussed as case studies. For context-coherence reasons, the present review focuses on metal and metal-oxide nanoparticles, i.e. carbon nanomaterials are not covered herein.

“…For example the presence of PPCPs is already detectable in surface water, as in ground water [1][2][3] and bioaccumulation of these persistent PPCPs in the aquatic life will become a threat to the environment [4,5]. PPCPs may often remain in the environment even after they have been consumed completely [3,[6][7][8][9][10] because PPCPs usually have long shelf lives to meet customer's demands, and some PPCPs are inadvertently dumped into environment; therefore, PPCPs are typical examples of so-called emerging contaminants [9,10]. Oxybenzone (the structure of which is shown in scheme 1) is a component of many sunscreen lotions, is regarded as typical emerging contaminants with high environmental risk.…”

Oxybenzone, one of the most often detected pharmaceuticals and personal care products (PPCPS), from aqueous solutions and this PPCPs removal from water had been studied by using the highly porous metal-organic framework (MOF) ) MIL-101(Cr) and a modified MIL-101(Cr) called MIL-101-OH. Adsorption results showed that MIL-101-OH which contains functional group such as -OH, which was very effective for oxybenzone adsorption. The adsorption performance of MIL-101-OH over MIL-101-OH was found to be greater than that of MIL-101(Cr), which means the functionalization of primitive MOFs have a positive effect on adsorption. The kinetics of MIL-101-OH also showed higher result compare to MIL-101(Cr). So along with a high adsorption capacity and repaid adsorption which is important for commercial applications.
