This work draws attention to both prospects and challenges for silica monoliths in solid-liquid catalysis at ultrahigh efficiency. The fundamental advantages of silica monoliths as support structure over particulate fixed beds and organicpolymer monoliths are illustrated as well as recent applications as flow-through microreactors for the production of fine chemicals. Preparation routes to sol-gel and porous glass-based silica monoliths featuring a hierarchical pore structure are described and their potential use as short-contact-time reactors is highlighted together with a view on the multiscale characterization and their rational design by establishing quantitative synthesis-morphology-transport relationships.

“…Therefore, they need to be further fabricated via pelletization or granulation process with the aid of binders or additives, which can often lead to significant loss in their adsorption performance (Williams, 2001;Davis, 2002;Kadib et al, 2009;Lohe et al, 2009;Wen et al, 2010;Hao et al, 2011). Correspondingly, it is of great promise to directly prepare carbon adsorbents with ordered macroscopic morphologies.…”

CO 2 capture represents the key technology for CO 2 reduction within the framework of CO 2 capture, utilization, and storage (CCUS). In fact, the implementation of CO 2 capture extends far beyond CCUS since it will link the CO 2 emission and recycling sectors, and when renewables are used to provide necessary energy input, CO 2 capture would enable a profitable zero-or even negative-emitting and integrated energy-chemical solution. To this end, highly efficient CO 2 capture technologies are needed, and adsorption using solid adsorbents has the potential to be one of the ideal options. Currently, the greatest challenge in this area is the development of adsorbents with high performance that balances a range of optimization-needed factors, those including costs, efficiency, and engineering feasibility. In this review, recent advances on the development of carbon-based and immobilized organic amines-based CO 2 adsorbents are summarized, the selection of these particular categories of materials is because they are among the most developed low-temperature (<100°C) CO 2 adsorbents up to date, which showed important potential for practical deployment at pilot-scale in the near future. Preparation protocols, adsorption behaviors as well as pros and cons of each type of the adsorbents are presented, it was concluded that encouraging results have been achieved already, however, the development of more effective adsorbents for CO 2 capture remains challenging and further innovations in the design and synthesis of adsorbents are needed.Keywords: CCUS, CO 2 capture, adsorption, energy, material science INTRODUCTION CO 2 CAPTURE AND AN INTEGRATED ENERGY-CHEMICAL SOLUTIONThe atmospheric CO 2 concentration now exceeds 400 ppm (CO2Now.org, 2014), and its continuous increase is believed to be the major factor leading to global warming and climatic change (Crowley, 2000;Held and Soden, 2000;Patz et al., 2005). Kaya et al. and Hoffert et al. have quantified net CO 2 emissions in terms of population, economic activity, and energy-related factors using Eq. 1 (Kaya, 1995;Hoffert et al., 1998).where C is the net CO 2 emission, P is population, GDP is the gross domestic product that is used here as an indicator of economyrelated factor, and E is energy production. Therefore, GDP/P is the Per capita GDP, and E/GDP can be regarded as the energy intensity during production that is closely related to the efficiency of energy utilization. The last term, C/E, represents the carbon intensity during energy production. As for the development of the human society and life quality, it is improper to limit population and production, which means there is no solution to CO 2 reduction from the first and second term in Eq. 1. On the other hand, increase in the energy production/utilization efficiency and control of the carbon footprint during energy processes are the major strategies for CO 2 sequestration (third and fourth term in Eq. 1). The complete decarbonization of energy is believed to be the ultimate solution for the long-term sustainability, ...

“…Of particular importance is the ability to obtain accurate and reproducible control over the reaction conditions such as temperature, pressure and reaction solvent. [9,11] Furthermore, monolithic devices (microreactors containing a porous network of typically silica or other oxide materials) can be functionalized extensively with enzymes [12], magnetic nanoparticles [11] and other functional groups [12][13][14] in order to tailor their catalytic properties such as selectivity and activity. [10,15].…”

The impregnated Au-containing monolith was found to be less active than the thiol functionalized Au-containing material, attributable to the low metal surface area of the Au nanoparticles. The reaction on the thiol functionalized Au-containing monolith was found to depend strongly on the type of oxidant used: tert-butyl hydroperoxide (TBHP) was more active than H 2 O 2, likely due to the thiol induced hydrophobicity in the monolith.
