Effective cleanup of viscous crude oil spills remains a persistent and crippling challenge. Herein, this work presents a Joule-heated superhydrophobic flower-like Cu 8 (PO 3 OH) 2 (PO 4 ) 4 •7H 2 O-coated copper foam (SHB-CF@CP) for rapid cleanup of viscous crude oil spills via a facile strategy. The SHB-CF@CP shows outstanding water repellency and excellent stability of hydrophobicity in harsh environments. Due to the high electrical conductivity and thermal conductivity, it requires lower power energy consumption (less than 1 V of voltage input) to raise the temperature significantly, which dramatically reduces the viscosity of crude oil (from ∼2 × 10 5 to ∼60 mPa s) and then increases the oil absorption rate, effectively avoiding the poor mobility and ineffective absorption of viscous crude oil. Notably, the SHB-CF@CP can achieve continuous and quick cleanup of crude oil under in situ pumping force. The high-performance Joule-heated SHB-CF@ CP sorbent with a strong porous skeleton, corrosion resistance, and low predicted operational costs holds a promise of promoting its practical applications in the cleanup of intractable and large-area viscous oil spills.

The hydroxyls on SiC nanosheet provide local protons, stabilize the intermediates and localize the electrons for deep photoreduction of CO2.

To match nature's prowess at using enzymes to make desired motifs in a regioselective fashion, we explore the use of visible light for the selective oxidation of the hydroxyl group to the corresponding ketosaccharide. This highly admirable approach offers several advantages over the enzymatic approach in terms of yields, the scope of substrates. Herein we report the development of a simple visible-light-promoted selective oxidation of unprotected glucosides that allows for inexpensive access to valuable ketosaccharides building blocks. The method is employed on a variety of different natural and artificial glucosides, is operationally simple and scalable, and is applied to access ketosaccharides rapidly and inexpensively.
