Summary: Paraffin-selective adsorbents for ethane/ethylene separation were developed using surface-functionalized mesoporous silica adsorbents. The adsorbents exhibited reverse selectivity, becoming paraffin-selective due to enhanced van der Waal's interactions between the grafted ionic liquids and ethane. Various silica-based adsorbents functionalized with different loadings, anion, and cation types were synthesized and characterized. The adsorbents showed stable performance in pressure swing adsorption and breakthrough cyclic testing, with a breakthrough ethylene productivity of up to 1.2 mmol/g and a breakthrough selectivity of 2.4.

Summary: This study presents a facile and environmentally friendly method for synthesizing C, N co-doped mesoporous TiO2 nanocrystals, using IL-assisted microwave synthesis, resulting in small-sized TiO2 with well-developed mesoporous structure and abundant C, N dopants. The material exhibits high specific-surface area, excellent hydrophilicity, elevated valence-band edges, abundant defect levels, and narrowed band-gap, leading to improved visible-light absorption, reduced photogenerated electron-hole recombination, and rapid charge transfer and surface-catalyzed reactions.

Summary: Mesoporous silica nanospheres (MSNs) were synthesized under neutral conditions, avoiding the use of acid or base catalysis and improving environmental friendliness. The effects of temperature, co-surfactant, and ionic strength on the formation of MSNs are complicated, with high ionic strength shown to destroy the formation of MSNs. The addition of co-surfactant increases the particle size of MSNs but decreases their uniformity.

Summary: In this study, a sulfur cathode material with strong polysulfide adsorption capability was prepared by grafting cations onto the SBA-15 surface. The resulting Im-SBA-15/CNT hybrid showed promising application potential as a host material due to the strong adsorption of polysulfides by Im-SBA-15 and the successful electron conduction provided by CNT. The composite exhibited superior electrochemical performance, maintaining a capacity of 682.3 mAh/g sulfur even after 350 cycles.

Summary: Composite CO2 sorbents were obtained by impregnating an amino acid ionic liquid into mesoporous silica gel. At lower loadings, the sorption is fast and the capacity is proportional to the mass content of the ionic liquid. At higher loadings, the sorption rate decreases due to hindered mass transfer. An increase in CO2 concentration leads to faster sorption and higher capacity. Physical adsorption/absorption processes contribute more to total sorption capacity at higher CO2 concentrations.

Summary: Chevrel Phases, MxMo6S8, are a class of heterogenous catalysts with unique combination of low-coordinate molybdenum atoms, tuneable oxidation state, thermal stability, and dual Lewis acidity & basicity, making them excellent candidates for fundamental catalytic reactions. Recent developments in synthesis techniques have lessened historical constraints, but the catalytic community has been slow to adopt these advances. This review summarises five decades of catalytic reports, identifies trends and gaps within the literature, and provides perspective on future directions for the catalytic application of Chevrel Phases.

Summary: In this study, an Australian First Nations-first approach is chosen to understand the chemical elements, aiming to change the practice of chemistry by engaging with cultural heritage and knowledge. This approach acknowledges the unique position of Aboriginal and Torres Strait Islander peoples in the Australian context. The paper explores how this approach could be implemented in Sydney on Aboriginal lands, led by Aboriginal people and incorporating local knowledge. The work so far has involved two years of meetings and discussions to determine appropriate ways of collaboration, while reflecting on the impact of the Periodic Table and considering the contribution of Indigenous knowledges to a broader chemistry curriculum.
