Selective Electrocatalytic Oxidation of Phenol to Benzoquinone via Water Splitting Using a Nonprecious Metal‐Based Electrocatalyst

Advanced Energy and Sustainability Research, EarlyView.
A green process has been developed utilizing electrochemistry to convert inexpensive, readily available phenol derived from lignin into para‐benzoquinone, a valuable chemical widely used in the manufacturing and chemical industries. For the first time, a novel electrocatalytic oxidation system is achieved with high 96.2% conversion of phenols to para ...

Dynamic Active Site Evolution in Lanthanum‐Based Catalysts Dictates Ethane Chlorination Pathways

Angewandte Chemie, EarlyView.
LaOCl‐catalyzed C2H6 chlorination offers a low‐carbon route for polyvinyl chloride synthesis, yet structural evolution occurs under Cl2 conditions. We establish structural sensitivity in La‐catalyzed chlorination, and elucidate the size‐dependent chlorophilicity of LaCl3 and the role of hydroxyl groups in overchlorination, highlighting stabilization of

Charting the Path to Increased Oil Palm Output in Ghana Beyond Area Expansion: Technology or Managerial Capacity — Which Leads the Way?

Agribusiness, EarlyView.
ABSTRACT This study sets out to investigate the prospects for raising oil palm output in sub‐Saharan Africa, particularly Ghana, without further expansion of cropland. Given global concerns about oil palm's role in deforestation and land use change, the focus is on enhancing productivity on existing farmlands.

A Thorough Characterization of the Tellurocyanate Anion

Angewandte Chemie, EarlyView.
[K@crypt‐222][TeCN] was synthesized from KCN, Te, and crypt‐222 in acetone. We discuss fundamental properties of [TeCN]−: Single crystal X‐ray diffraction, nuclear magnetic resonance (13C, 15N, 125Te), vibrational spectroscopy, and negative ion photoelectron spectroscopy.
