“…Sodium aluminate (SA), a solid super base catalyst, cheap and easily available material finds interesting applications in organic transformations however, it is highly hygroscopic and corrosive, making its handling problematic. Blending, supporting or dispersing this highly reactive component would be a relevant strategy to optimize both catalytic activity and workability .…”

Mesoporous solid base catalysts are essential candidates for green and sustainable catalytic processes. In this work, novel mesoporous solid base catalysts was synthesized by promoting mesoporous supports with sodium aluminate (NaAlO2). The prepared catalysts are characterized using a wide variety of molecular and solid‐state techniques to determine their structural and textural properties. The catalysts texture was strongly affected by the promotion of sodium aluminate. The nature of the support and the sodium aluminate loading are shown to play a crucial role on the total basicity. In turn, these NaAlO2‐containing mesoporous materials showed high catalytic activity for Knoevenagel condensation under solvent free reaction conditions. The catalysts are truly heterogeneous without leaching any active sites and also showed good reusability.

“…and showed high catalytic performance. [19][20][21][22][23][24] Yet, NaAlO 2 is highly corrosive and hygroscopic, which makes it difficult to use industrially. In the laboratory, the operator can notice this by the fact that glass wares are corroded when in contact with pure NaAlO 2difficult to clean after use.…”

A significant obstacle in the large-scale applications of sodium borohydride (NaBH 4 ) for hydrogen storage is its high cost. Herein, we report a new method to synthesize NaBH 4 by ball milling hydrated sodium tetraborate (Na 2 B 4 O 7 • 10H 2 O) with low-cost Al or Al 88 Si 12 , instead of Na, Mg or Ca. An effective strategy is developed to facilitate mass transfer during the reaction by introducing NaH to enable the formation of NaAlO 2 instead of dense Al 2 O 3 on Al surface, and by using Si as a milling additive to prevent agglomeration and also break up passivation layers. Another advantage of this process is that hydrogen in Na 2 B 4 O 7 • 10H 2 O serves as a hydrogen source for NaBH 4 generation. Considering the low cost of the starting materials and simplicity in operation, our studies demonstrate the potential of producing NaBH 4 in a more economical way than the commercial process.
