Ordered mesoporous materials in catalysis

Ordered mesoporous materials

Siliceous ordered mesoporous materials are well-investigated and -covered by several excellent reviews. Less work has been directed to non-siliceous materials, although these could have more wide-ranging applications. This review will address the synthesis and properties of non-siliceous ordered mesoporous materials, covering oxidic, non-oxidic, metallic, and pure carbon frameworks. Organometallic frameworks, which are typically not synthesized in the presence of surfactants, are beyond the scope of this paper.

Non-siliceous Mesostructured and Mesoporous Materials†

This review paper deals with proven and potential applications of mesoporous molecular sieves in catalysis. In addition to introduction and conclusion, the text is divided into two parts, respectively, dedicated to the design of solid catalysts and catalyst supports and to some relevant examples of catalytic processes.

Renewable energy is considered crucial for climate change mitigation that can limit global warming to 1.5–2 °C. However, the impact of capacity expansion of renewables on the sustainability dimensions has not been rigorously assessed for the Indian scenario. In this perspective, the present research investigates the optimal capacity installation of renewables using a proposed modelling framework. The framework encompasses a multi-objective optimization model interlinked to a sustainability model. This work develops a simplified temporally resolved electricity model of India to explore nine broad scenarios. The Pareto front solutions are ranked under a set of decision-maker preference scenarios across six sustainability metrics, including economic dispatchability, emission, water-use, land-use, safety, and employment. Results indicate a possibility of 25.5%–41.2% of renewable penetration by 2030. The Pareto frontiers with a higher share of onshore wind, utility solar photovoltaic, and dammed hydro are among the top-ranked solutions. High river hydro supported by high levels of offshore wind can significantly contribute to low carbon generation without overshooting the upfront cost. Overall, the electricity mix with the least coal power generation of 1175 TWh/yr estimates to be the most sustainable solution. This paper addresses the sensitivity to changes in input lifetime year and cost assumptions; output shows considerable robustness of annual system costs to the lifetime of technologies and higher sensitivity to utility solar and onshore wind costs.

Low carbon electricity system for India in 2030 based on multi-objective multi-criteria assessment

Smart grid – the automation of electric grid is an emerging basket of interdisciplinary technologies, aimed towards bringing a revolution in the management of electricity networks. The benefits, risks and challenges involved in smart grid and compared with the existing grid are analysed so as to point out the motivational drivers for a change in electricity network. The constituents of smart grid, role of geographic information system and grid modernization index and the impact of projects that have been deployed globally are discussed. Special emphasis has been given on such projects in India. The article emphasizes on the importance of modernization of present-day utility grid for the generation of sustainable and reliable energy.
